[PATCH v2] mtd: rawnand: marvell: fix the chip-select DT parsing logic

by Miquel Raynal

The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left. Furthermore, for both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings. Finally, the 'reg' property of a 'nand' node (with the new bindings) gives the IDs of each CS line in use. marvell_nand.c driver first look at the number of CS lines that are present in this property. Better use of_property_count_elems_of_size() than dividing by 4 the size of the number of bytes returned by of_get_property().

[PATCH] gpioib: do not free unrequested descriptors

by Timur Tabi

If the main loop in linehandle_create() encounters an error, it unwinds completely by freeing all previously requested GPIO descriptors. However, if the error occurs in the beginning of the loop before that GPIO is requested, then the exit code attempts to free a null descriptor. If extrachecks is enabled, gpiod_free() triggers a WARN_ON. Instead, keep a separate count of legitimate GPIOs so that only those are freed.

[PATCH v3][for 4.17-rc3] cpufreq / CPPC: Set platform specific transition_delay_us

by Prashanth Prakash

Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit "3d41386d556d: cpufreq: CPPC: Use transition_delay_us depending transition_latency" we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. With this on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

Revert f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") from stable trees

by Mika Westerberg

Hi, It seems that commit f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") can cause problems on some Skylake systems with Sunrisepoint PCH-H. Namely on certain systems it may turn the backlight PWM pin from native mode to GPIO which makes the screen blank during boot. There is more information here: https://bugzilla.redhat.com/show_bug.cgi?id=1543769 The actual reason is that GPIO numbering used in BIOS is using "Windows" numbers meaning that they don't match the hardware 1:1 and because of this a wrong pin (backlight PWM) is picked and switched to GPIO mode. There is a proper fix for this but since it has quite many dependencies on commits that cannot be considered stable material, I suggest we revert commit f5a26acf0162 from stable trees 4.9, 4.14 and 4.15 to prevent the backlight issue. Thanks!

[PATCH] ALSA: dice: fix error path to destroy initialized stream data

by Takashi Sakamoto

In error path of snd_dice_stream_init_duplex(), stream data for incoming packet can be left to be initialized. This commit fixes it.

[PATCH 01/11] PM / Domains: Fix error path during attach in genpd

by Ulf Hansson

In case the PM domain fails to be powered on in genpd_dev_pm_attach(), it returns -EPROBE_DEFER, but keeping the device attached to its PM domain. This leads to problems when the next attempt to attach is re-tried. More precisely, in that situation an -EEXIST error code is returned, because the device already has its PM domain pointer assigned, from the first attempt. Now, because of the sloppy error handling by the existing callers of dev_pm_domain_attach(), probing is allowed to continue when -EEXIST is returned. However, in such case there are no guarantees that the PM domain is powered on by genpd, which may lead to hangs when buses/drivers tried to access their devices. Let's fix this behaviour, simply by detaching the device when powering on fails in genpd_dev_pm_attach().

File /sys/kernel/debug/kprobes/blacklist displays random addresses: [root@s8360046 linux]# cat /sys/kernel/debug/kprobes/blacklist 0x0000000047149a90-0x00000000bfcb099a print_type_x8 .... This breaks 'perf probe' which uses the blacklist file to prohibit probes on certain functions by checking the address range. Fix this by printing the correct (unhashed) address. The file mode is read all but this is not an issue as the file hierarchy points out: # ls -ld /sys/ /sys/kernel/ /sys/kernel/debug/ /sys/kernel/debug/kprobes/ /sys/kernel/debug/kprobes/blacklist dr-xr-xr-x 12 root root 0 Apr 19 07:56 /sys/ drwxr-xr-x 8 root root 0 Apr 19 07:56 /sys/kernel/ drwx------ 16 root root 0 Apr 19 06:56 /sys/kernel/debug/ drwxr-xr-x 2 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/ -r--r--r-- 1 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/blacklist Everything in and below /sys/kernel/debug is rwx to root only, no group or others have access. Background: Directory /sys/kernel/debug/kprobes is created by debugfs_create_dir() which sets the mode bits to rwxr-xr-x. Maybe change that to use the parent's directory mode bits instead?

This is a note to let you know that I've just added the patch titled ARM: amba: Fix race condition with driver_override to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
