[PATCH] leds: class: Revert: "If no default trigger is given, make hw_control trigger the default trigger"

by Hans de Goede

Commit 66601a29bb23 ("leds: class: If no default trigger is given, make hw_control trigger the default trigger") causes ledtrig-netdev to get set as default trigger on various network LEDs. This causes users to hit a pre-existing AB-BA deadlock issue in ledtrig-netdev between the LED-trigger locks and the rtnl mutex, resulting in hung tasks in kernels >= 6.9. Solving the deadlock is non trivial, so for now revert the change to set the hw_control trigger as default trigger, so that ledtrig-netdev no longer gets activated automatically for various network LEDs. The netdev trigger is not needed because the network LEDs are usually under hw-control and the netdev trigger tries to leave things that way so setting it as the active trigger for the LED class device is a no-op.

[git:media_stage/master] media: uvcvideo: Fix integer overflow calculating timestamp

by Laurent Pinchart

This is an automatic generated email to let you know that the following patch were queued: Subject: media: uvcvideo: Fix integer overflow calculating timestamp Author: Ricardo Ribalda <ribalda(a)chromium.org> Date: Mon Jun 10 19:17:49 2024 +0000 The function uvc_video_clock_update() supports a single SOF overflow.

If a large number of CMA memory are configured in system (for example, the CMA memory accounts for 50% of the system memory), starting a virtual machine with device passthrough will get stuck. During starting the virtual machine, it will call pin_user_pages_remote(..., FOLL_LONGTERM, ...) to pin memory. Normally if a page is present and in CMA area, pin_user_pages_remote() will migrate the page from CMA area to non-CMA area because of FOLL_LONGTERM flag. But if non-movable allocation requests return CMA memory, migrate_longterm_unpinnable_pages() will migrate a CMA page to another CMA page, which will fail to pass the check in check_and_migrate_movable_pages() and cause migration endless. Call trace: pin_user_pages_remote --__gup_longterm_locked // endless loops in this function ----_get_user_pages_locked ----check_and_migrate_movable_pages ------migrate_longterm_unpinnable_pages --------alloc_migration_target This problem will also have a negative impact on CMA itself. For example, when CMA is borrowed by THP, and we need to reclaim it through cma_alloc() or dma_alloc_coherent(), we must move those pages out to ensure CMA's users can retrieve that contigous memory. Currently, CMA's memory is occupied by non-movable pages, meaning we can't relocate them. As a result, cma_alloc() is more likely to fail. To fix the problem above, we add one PCP list for THP, which will not introduce a new cacheline for struct per_cpu_pages.

[PATCH V2] mm/page_alloc: Separate THP PCP into movable and non-movable categories

by yangge1116＠126.com

From: yangge <yangge1116(a)126.com> Since commit 5d0a661d808f ("mm/page_alloc: use only one PCP list for THP-sized allocations") no longer differentiates the migration type of pages in THP-sized PCP list, it's possible that non-movable allocation requests may get a CMA page from the list, in some cases, it's not acceptable. If a large number of CMA memory are configured in system (for example, the CMA memory accounts for 50% of the system memory), starting a virtual machine with device passthrough will get stuck. During starting the virtual machine, it will call pin_user_pages_remote(..., FOLL_LONGTERM, ...) to pin memory. Normally if a page is present and in CMA area, pin_user_pages_remote() will migrate the page from CMA area to non-CMA area because of FOLL_LONGTERM flag. But if non-movable allocation requests return CMA memory, migrate_longterm_unpinnable_pages() will migrate a CMA page to another CMA page, which will fail to pass the check in check_and_migrate_movable_pages() and cause migration endless. Call trace: pin_user_pages_remote --__gup_longterm_locked // endless loops in this function ----_get_user_pages_locked ----check_and_migrate_movable_pages ------migrate_longterm_unpinnable_pages --------alloc_migration_target This problem will also have a negative impact on CMA itself. For example, when CMA is borrowed by THP, and we need to reclaim it through cma_alloc() or dma_alloc_coherent(), we must move those pages out to ensure CMA's users can retrieve that contigous memory. Currently, CMA's memory is occupied by non-movable pages, meaning we can't relocate them. As a result, cma_alloc() is more likely to fail. To fix the problem above, we add one PCP list for THP, which will not introduce a new cacheline for struct per_cpu_pages. THP will have 2 PCP lists, one PCP list is used by MOVABLE allocation, and the other PCP list is used by UNMOVABLE allocation. MOVABLE allocation contains GPF_MOVABLE, and UNMOVABLE allocation contains GFP_UNMOVABLE and GFP_RECLAIMABLE.

[PATCH AUTOSEL 6.9 01/28] usb: gadget: uvc: configfs: ensure guid to be valid before set

by Sasha Levin

[PATCH AUTOSEL 6.9 01/35] ssb: Fix potential NULL pointer dereference in ssb_device_uevent()

by Sasha Levin

From: Rand Deeb <rand.sec96(a)gmail.com> [ Upstream commit 789c17185fb0f39560496c2beab9b57ce1d0cbe7 ] The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attempting to use it.

[PATCH 1/7] OPP: Fix support for required OPPs for multiple PM domains

by Ulf Hansson

In _set_opp() we are normally bailing out when trying to set an OPP that is the current one. This make perfect sense, but becomes a problem when _set_required_opps() calls it recursively. More precisely, when a required OPP is being shared by multiple PM domains, we end up skipping to request the corresponding performance-state for all of the PM domains, but the first one. Let's fix the problem, by calling _set_opp_level() from _set_required_opps() instead.

Candidates for stable v6.9..v6.10-rc1 Use After Free

by Ronnie Sahlberg

These commits reference use.after.free between v6.9 and v6.10-rc1 These commits are not, yet, in stable/linux-rolling-stable. Let me know if you would rather me compare to a different repo/branch. The list has been manually pruned to only contain commits that look like actual issues. If they contain a Fixes line it has been verified that at least one of the commits that the Fixes tag(s) reference is in stable/linux-rolling-stable 90e823498881fb8a91d8 5c9c5d7f26acc2c669c1 573601521277119f2e2b f88da7fbf665ffdcbf5b 47a92dfbe01f41bcbf35 5bc9de065b8bb9b8dd87 5f204051d998ec3d7306 be84f32bb2c981ca6709 88ce0106a1f603bf360c -- Ronnie Sahlberg [Principal Software Engineer, Linux] P 775 384 8203 | E [email] | W ciq.com

Either backport e5e1c2097881 because you think that warning should be in 5.10.x, or don't backport it. Best regards Uwe

[PATCH v2] ata: ahci: Do not enable LPM if no LPM states are supported by the HBA

by Niklas Cassel

LPM consists of HIPM (host initiated power management) and DIPM (device initiated power management). ata_eh_set_lpm() will only enable HIPM if both the HBA and the device supports it. However, DIPM will be enabled as long as the device supports it. The HBA will later reject the device's request to enter a power state that it does not support (Slumber/Partial/DevSleep) (DevSleep is never initiated by the device). For a HBA that doesn't support any LPM states, simply don't set a LPM policy such that all the HIPM/DIPM probing/enabling will be skipped. Not enabling HIPM or DIPM in the first place is safer than relying on the device following the AHCI specification and respecting the NAK. (There are comments in the code that some devices misbehave when receiving a NAK.) Performing this check in ahci_update_initial_lpm_policy() also has the advantage that a HBA that doesn't support any LPM states will take the exact same code paths as a port that is external/hot plug capable. Side note: the port in ata_port_dbg() has not been given a unique id yet, but this is not overly important as the debug print is disabled unless explicitly enabled using dynamic debug. A follow-up series will make sure that the unique id assignment will be done earlier. For now, the important thing is that the function returns before setting the LPM policy.

[PATCH v2] riscv: dts: starfive: Set EMMC vqmmc maximum voltage to 3.3V on JH7110 boards

by Shengyu Qu

Currently, for JH7110 boards with EMMC slot, vqmmc voltage for EMMC is fixed to 1.8V, while the spec needs it to be 3.3V on low speed mode and should support switching to 1.8V when using higher speed mode. Since there are no other peripherals using the same voltage source of EMMC's vqmmc(ALDO4) on every board currently supported by mainline kernel, regulator-max-microvolt of ALDO4 should be set to 3.3V.

[PATCH v2] xhci: Apply XHCI_RESET_TO_DEFAULT quirk to TGL

by Reka Norman

TGL systems have the same issue as ADL, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to TGL as well. The issue it fixes is a ~20s boot time delay when booting from S5. It affects TGL devices, and TGL support was added starting from v5.3.

[PATCHv3 6.6.y 0/3] Fix missing lib.sh for net/unicast_extensions.sh and net/pmtu.sh tests

by Po-Hsu Lin

Since upstream commit: * 0f4765d0 "selftests/net: convert unicast_extensions.sh to run it in unique namespace" * 378f082e "selftests/net: convert pmtu.sh to run it in unique namespace" The lib.sh from commit 25ae948b "selftests/net: add lib.sh" will be needed. Otherwise these test will complain about missing files and fail: $ sudo ./unicast_extensions.sh ./unicast_extensions.sh: line 31: lib.sh: No such file or directory ... $ sudo ./pmtu.sh ./pmtu.sh: line 201: lib.sh: No such file or directory ./pmtu.sh: line 941: cleanup_all_ns: command not found ... Another commit b6925b4e "selftests/net: add variable NS_LIST for lib.sh" is needed to add support for the cleanup_all_ns above. And 2114e833 "selftests: forwarding: Avoid failures to source net/lib.sh" is a follow-up fix for tests inside the net/forwarding directory. V2: Add 2114e833 "selftests: forwarding: Avoid failures to source net/lib.sh" as suggested by Hangbin Liu. V3: Adjust commit 25ae948b to add lib.sh directly to TEST_FILES in Makefile, as we already have upstream commit 06efafd8 that would make this change landed in 6.6.y.

[PATCH 6.1] Revert "fork: defer linking file vma until vma is fully initialized"

This reverts commit 0c42f7e039aba3de6d7dbf92da708e2b2ecba557. The backport is incomplete and causes xfstests failures. The consequences of the incomplete backport seem worse than the original issue, so pick the lesser evil and revert until a full backport is ready.

[PATCH -stable,5.4] netfilter: nftables: exthdr: fix 4-byte stack OOB write

by Pablo Neira Ayuso

From: Florian Westphal <fw(a)strlen.de> commit fd94d9dadee58e09b49075240fe83423eb1dcd36 upstream. If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption. This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does. The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added. Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961). Fixes: 49499c3e6e18 ("netfilter: nf_tables: switch registers to 32 bit addressing") Fixes: 935b7f643018 ("netfilter: nft_exthdr: add TCP option matching") Fixes: 133dc203d77d ("netfilter: nft_exthdr: Support SCTP chunks") Fixes: dbb5281a1f84 ("netfilter: nf_tables: add support for matching IPv4 options") Signed-off-by: Florian Westphal <fw(a)strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo(a)netfilter.org> --- Hi Greg, Sasha, This backport is missing in 5.4, please apply to -stable.

Bug in Kernel 6.8.x, 6.9.x Causing Trace/Panic During Shutdown/Reboot

by Ilkka Naulapää

Greetings fellas, I have encountered a critical bug in the Linux vanilla kernel that leads to a kernel panic during the shutdown or reboot process. The issue arises after all services, including `journald`, have been stopped. As a result, the machine fails to complete the shutdown or reboot procedure, effectively causing the system to hang and not shut down or reboot. Here are the details of the issue: - Affected Versions: Before kernel version 6.8.10, the bug caused a quick display of a kernel trace dump before the shutdown/reboot completed. Starting from version 6.8.10 and continuing into version 6.9.0 and 6.9.1, this issue has escalated to a kernel panic, preventing the shutdown or reboot from completing and leaving the machine stuck. - Symptoms: - In normal shutdown/reboot scenarios, the kernel trace dump briefly appears as the last message on the screen. - In rescue mode, the kernel panic message is displayed. Normally it is not shown. Since `journald` is stopped before this issue occurs, no textual logs are available. However, I have captured two pictures illustrating these related issues, which I am attaching to this email for your reference. Also added my custom kernel config. Thank you for your attention to this matter. Please let me know if any additional information is required to assist in diagnosing and resolving this bug. Best regards, Ilkka Naulapää

[PATCH] net: usb: ax88179_178a: improve reset check

by Jose Ignacio Tornos Martinez

After ecf848eb934b ("net: usb: ax88179_178a: fix link status when link is set to down/up") to not reset from usbnet_open after the reset from usbnet_probe at initialization stage to speed up this, some issues have been reported. It seems to happen that if the initialization is slower, and some time passes between the probe operation and the open operation, the second reset from open is necessary too to have the device working. The reason is that if there is no activity with the phy, this is "disconnected". In order to improve this, the solution is to detect when the phy is "disconnected", and we can use the phy status register for this. So we will only reset the device from reset operation in this situation, that is, only if necessary. The same bahavior is happening when the device is stopped (link set to down) and later is restarted (link set to up), so if the phy keeps working we only need to enable the mac again, but if enough time passes between the device stop and restart, reset is necessary, and we can detect the situation checking the phy status register too. cc: stable(a)vger.kernel.org # 6.6+ Fixes: ecf848eb934b ("net: usb: ax88179_178a: fix link status when link is set to down/up") Reported-by: Yongqin Liu <yongqin.liu(a)linaro.org> Reported-by: Antje Miederhöfer <a.miederhoefer(a)gmx.de> Reported-by: Arne Fitzenreiter <arne_f(a)ipfire.org> Tested-by: Yongqin Liu <yongqin.liu(a)linaro.org> Tested-by: Antje Miederhöfer <a.miederhoefer(a)gmx.de> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- drivers/net/usb/ax88179_178a.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) diff --git a/drivers/net/usb/ax88179_178a.c b/drivers/net/usb/ax88179_178a.c index 51c295e1e823..c2fb736f78b2 100644 --- a/drivers/net/usb/ax88179_178a.c +++ b/drivers/net/usb/ax88179_178a.c @@ -174,7 +174,6 @@ struct ax88179_data { u32 wol_supported; u32 wolopts; u8 disconnecting; - u8 initialized; }; struct ax88179_int_data { @@ -1678,12 +1677,21 @@ static int ax88179_reset(struct usbnet *dev) static int ax88179_net_reset(struct usbnet *dev) { - struct ax88179_data *ax179_data = dev->driver_priv; + u16 tmp16; - if (ax179_data->initialized) + ax88179_read_cmd(dev, AX_ACCESS_PHY, AX88179_PHY_ID, GMII_PHY_PHYSR, + 2, &tmp16); + if (tmp16) { + ax88179_read_cmd(dev, AX_ACCESS_MAC, AX_MEDIUM_STATUS_MODE, + 2, 2, &tmp16); + if (!(tmp16 & AX_MEDIUM_RECEIVE_EN)) { + tmp16 |= AX_MEDIUM_RECEIVE_EN; + ax88179_write_cmd(dev, AX_ACCESS_MAC, AX_MEDIUM_STATUS_MODE, + 2, 2, &tmp16); + } + } else { ax88179_reset(dev); - else - ax179_data->initialized = 1; + } return 0; } -- 2.45.1

[PATCH 2/2] pwm: stm32: Fix calculation of prescaler

by Uwe Kleine-König

A small prescaler is beneficial, as this improves the resolution of the duty_cycle configuration. However if the prescaler is too small, the maximal possible period becomes considerably smaller than the requested value. One situation where this goes wrong is the following: With a parent clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for period = 941243 ns currently results in PSC = 1. The value for ARR is then calculated to PSC = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301 This value is bigger than 65535 however and so doesn't fit into the respective register. In this particular case the PWM was configured for a period of 313733.4806027616 ns (with ARR = 98301 & 0xffff). Even if ARR was configured to its maximal value, only period = 627495.6861167669 ns would be achievable. Fix the calculation accordingly and adapt the comment to match the new algorithm. With the calculation fixed the above case results in PSC = 2 and so an actual period of 941229.1667195285 ns.

[PATCH 4.19.y] hugetlb_encode.h: fix undefined behaviour (34 << 26)

by Carlos Llamas

From: Matthias Goergens <matthias.goergens(a)gmail.com> commit 710bb68c2e3a24512e2d2bae470960d7488e97b1 upstream. Left-shifting past the size of your datatype is undefined behaviour in C. The literal 34 gets the type `int`, and that one is not big enough to be left shifted by 26 bits. An `unsigned` is long enough (on any machine that has at least 32 bits for their ints.) For uniformity, we mark all the literals as unsigned. But it's only really needed for HUGETLB_FLAG_ENCODE_16GB. Thanks to Randy Dunlap for an initial review and suggestion.

However, unlike the mpt3sas driver, the mpi3mr driver does not define the sas_ncq_prio_supported and sas_ncq_prio_enable sysfs attributes, so the ncq_prio_enable field of struct mpi3mr_sdev_priv_data is never actually set and NCQ Priority cannot ever be used. Fix this by defining these missing atributes to allow a user to check if an ATA device supports NCQ priority and to enable/disable the use of NCQ priority. To do this, lift the function scsih_ncq_prio_supp() out of the mpt3sas driver and make it the generic SCSI SAS transport function sas_ata_ncq_prio_supported().

[PATCH 5.4.y] hv_utils: drain the timesync packets on onchannelcallback

by Dexuan Cui

From: Vineeth Pillai <viremana(a)linux.microsoft.com> commit b46b4a8a57c377b72a98c7930a9f6969d2d4784e There could be instances where a system stall prevents the timesync packets to be consumed. And this might lead to more than one packet pending in the ring buffer. Current code empties one packet per callback and it might be a stale one. So drain all the packets from ring buffer on each callback. Signed-off-by: Vineeth Pillai <viremana(a)linux.microsoft.com> Reviewed-by: Michael Kelley <mikelley(a)microsoft.com> Link: https://lore.kernel.org/r/20200821152849.99517-1-viremana@linux.microsoft.c… Signed-off-by: Wei Liu <wei.liu(a)kernel.org> The old code in the upstream commit uses HV_HYP_PAGE_SIZE, but the old code in 5.4.y sitll uses PAGE_SIZE. Fixed this manually for 5.4.y. Note: 5.4.y already has the define HV_HYP_PAGE_SIZE, so the new code in in the upstream commit works for 5.4.y. If there are multiple messages in the host-to-guest ringbuffer of the TimeSync device, 5.4.y only handles 1 message, and later the host puts new messages into the ringbuffer without signaling the guest because the ringbuffer is not empty, causing a "hung" ringbuffer. Backported the mainline fix for this issue.

In this case tick_setup_device() calls tick_take_do_timer_from_boot() to update tick_do_timer_cpu and this triggers the WARN_ON_ONCE(irqs_disabled) in smp_call_function_single().

[PATCHv2 6.6.y 0/3] Fix missing lib.sh for net/unicast_extensions.sh and net/pmtu.sh tests

by Po-Hsu Lin

Since upstream commit: * 0f4765d0 "selftests/net: convert unicast_extensions.sh to run it in unique namespace" * 378f082e "selftests/net: convert pmtu.sh to run it in unique namespace" The lib.sh from commit 25ae948b "selftests/net: add lib.sh" will be needed. Otherwise these test will complain about missing files and fail: $ sudo ./unicast_extensions.sh ./unicast_extensions.sh: line 31: lib.sh: No such file or directory ... $ sudo ./pmtu.sh ./pmtu.sh: line 201: lib.sh: No such file or directory ./pmtu.sh: line 941: cleanup_all_ns: command not found ... Another commit b6925b4e "selftests/net: add variable NS_LIST for lib.sh" is needed to add support for the cleanup_all_ns above. And 2114e833 "selftests: forwarding: Avoid failures to source net/lib.sh" is a follow-up fix for tests inside the net/forwarding directory. V2: Add 2114e833 "selftests: forwarding: Avoid failures to source net/lib.sh" as suggested by Hangbin Liu.

[PATCH 0/3] swiotlb: Backport to linux-stable 6.6

by Fabio Estevam

This series of swiotlb patches fixes a iwlwifi regression on the i.MX8MM IoT Gateway board running kernel 6.6. This was noticed when updating the kernel from 5.10 to 6.6. Without this series, the board cannot boot kernel 6.6 due to the storm of alignment errors from the iwlwifi driver. This has been reported and discussed in the linux-wireless list: https://lore.kernel.org/linux-wireless/CAOMZO5D2Atb=rnvmNLvu8nrsn+3L9X9NbG1… Will Deacon suggested: "If you want to backport that change, then I think you should probably take the whole series: https://lore.kernel.org/all/20240308152829.25754-1-will@kernel.org/ (and there were some follow-ups from Michael iirc; you're best off checking the git history for kernel/dma/swiotlb.c). FWIW: we have this series backported to 6.6 in the android15-6.6 tree." From this series, only the two patches below are not present in the 6.6 stable tree: swiotlb: Enforce page alignment in swiotlb_alloc() swiotlb: Reinstate page-alignment for mappings >= PAGE_SIZE While at it, also backport: swiotlb: extend buffer pre-padding to alloc_align_mask if necessary as it fixes a commit that is present in 6.6. Petr Tesarik (1): swiotlb: extend buffer pre-padding to alloc_align_mask if necessary Will Deacon (2): swiotlb: Enforce page alignment in swiotlb_alloc() swiotlb: Reinstate page-alignment for mappings >= PAGE_SIZE kernel/dma/swiotlb.c | 83 +++++++++++++++++++++++++++++++++----------- 1 file changed, 63 insertions(+), 20 deletions(-) -- 2.34.1

For any dc validate we will always remove all current planes and add new planes. However when switching from no planes to 1 plane, ODM mode is not reset because no planes get removed. This has caused an issue where we kept ODM combine when it should have been remove when a plane is added. The change is to reset ODM mode when adding the first plane.

Since the asid is allocated in the vm create ioctl, rather erase it when closing the vm, prior to dropping the potential last ref. This should also work when user closes driver fd without explicit vm destroy.

by Giovanni Santini

Hi everyone, I am writing to report the issue mentioned in the subject. Essentially, when running an executable from a compressed folder in an NTFS partition mounted via ntfs3 I get a segfault. The error line I get in dmesg is: ntfs3: nvme0n1p5: ino=c3754, "hello" mmap(write) compressed not supported I've attached a terminal script where I show my source, Makefile and how the error appears. Bests, -- Giovanni Santini

[PATCH v5] usb: dwc3: core: Workaround for CSR read timeout

From: Jos Wang <joswang(a)lenovo.com> This is a workaround for STAR 4846132, which only affects DWC_usb31 version2.00a operating in host mode.

[PATCH v4, 3/3] usb: dwc3: core: Workaround for CSR read timeout

by joswang

From: Jos Wang <joswang(a)lenovo.com> This is a workaround for STAR 4846132, which only affects DWC_usb31 version2.00a operating in host mode. There is a problem in DWC_usb31 version 2.00a operating in host mode that would cause a CSR read timeout When CSR read coincides with RAM Clock Gating Entry. By disable Clock Gating, sacrificing power consumption for normal operation.

[PATCH 5.15.y] hugetlb_encode.h: fix undefined behaviour (34 << 26)

by Carlos Llamas

From: Matthias Goergens <matthias.goergens(a)gmail.com> commit 710bb68c2e3a24512e2d2bae470960d7488e97b1 upstream. Left-shifting past the size of your datatype is undefined behaviour in C. The literal 34 gets the type `int`, and that one is not big enough to be left shifted by 26 bits. An `unsigned` is long enough (on any machine that has at least 32 bits for their ints.) For uniformity, we mark all the literals as unsigned. But it's only really needed for HUGETLB_FLAG_ENCODE_16GB. Thanks to Randy Dunlap for an initial review and suggestion.

[PATCH 2/3] spi: stm32: qspi: Clamp stm32_qspi_get_mode() output to CCR_BUSWIDTH_4

by patrice.chotard＠foss.st.com

From: Patrice Chotard <patrice.chotard(a)foss.st.com> In case usage of OCTAL mode, buswidth parameter can take the value 8. As return value of stm32_qspi_get_mode() is used to configure fields of CCR registers that are 2 bits only (fields IMODE, ADMODE, ADSIZE, DMODE), clamp return value of stm32_qspi_get_mode() to 4.

SMN accesses are done indirectly through an index/data pair in PCI config space. The PCI config access may fail and return an error code. This would prevent the "read" value from being updated. However, the PCI config access may succeed, but the return value may be invalid. This is in similar fashion to PCI bad reads, i.e. return all bits set. Most systems will return 0 for SMN addresses that are not accessible. This is in line with AMD convention that unavailable registers are Read-as-Zero/Writes-Ignored. However, some systems will return a "PCI Error Response" instead. This value, along with an error code of 0 from the PCI config access, will confuse callers of the amd_smn_read() function.
