Dell AIO had LineOut jack. Add LineOut verb into this patch. [ Additional notes: the ALC274 codec seems requiring the fixed pin / DAC connections for HP / line-out pins for enabling EQ for speakers; i.e. the HP / LO pins expect to be connected with NID 0x03 while keeping the speaker with NID 0x02. However, by adding a new line-out pin, the auto-parser assigns the NID 0x02 for HP/LO pins as primary outputs. As an easy workaround, we provide the preferred_pairs[] to map forcibly for these pins. -- tiwai ] Fixes: 75ee94b20b46 ("ALSA: hda - fix headset mic problem for Dell machines with alc274") Signed-off-by: Kailang Yang <kailang(a)realtek.com> Signed-off-by: Takashi Iwai <tiwai(a)suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- sound/pci/hda/patch_realtek.c | 35 ++++++++++++++++++++++++++++++++++- 1 file changed, 34 insertions(+), 1 deletion(-) --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -5162,6 +5162,22 @@ static void alc233_alc662_fixup_lenovo_d } } +/* Forcibly assign NID 0x03 to HP/LO while NID 0x02 to SPK for EQ */ +static void alc274_fixup_bind_dacs(struct hda_codec *codec, + const struct hda_fixup *fix, int action) +{ + struct alc_spec *spec = codec->spec; + static hda_nid_t preferred_pairs[] = { + 0x21, 0x03, 0x1b, 0x03, 0x16, 0x02, + 0 + }; + + if (action != HDA_FIXUP_ACT_PRE_PROBE) + return; + + spec->gen.preferred_dacs = preferred_pairs; +} + /* for hda_fixup_thinkpad_acpi() */ #include "thinkpad_helper.c" @@ -5279,6 +5295,8 @@ enum { ALC233_FIXUP_LENOVO_MULTI_CODECS, ALC294_FIXUP_LENOVO_MIC_LOCATION, ALC700_FIXUP_INTEL_REFERENCE, + ALC274_FIXUP_DELL_BIND_DACS, + ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, }; static const struct hda_fixup alc269_fixups[] = { @@ -6089,6 +6107,21 @@ static const struct hda_fixup alc269_fix {} } }, + [ALC274_FIXUP_DELL_BIND_DACS] = { + .type = HDA_FIXUP_FUNC, + .v.func = alc274_fixup_bind_dacs, + .chained = true, + .chain_id = ALC269_FIXUP_DELL1_MIC_NO_PRESENCE + }, + [ALC274_FIXUP_DELL_AIO_LINEOUT_VERB] = { + .type = HDA_FIXUP_PINS, + .v.pins = (const struct hda_pintbl[]) { + { 0x1b, 0x0401102f }, + { } + }, + .chained = true, + .chain_id = ALC274_FIXUP_DELL_BIND_DACS + }, }; static const struct snd_pci_quirk alc269_fixup_tbl[] = { @@ -6550,7 +6583,7 @@ static const struct snd_hda_pin_quirk al {0x14, 0x90170110}, {0x1b, 0x90a70130}, {0x21, 0x03211020}), - SND_HDA_PIN_QUIRK(0x10ec0274, 0x1028, "Dell", ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, + SND_HDA_PIN_QUIRK(0x10ec0274, 0x1028, "Dell", ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, {0x12, 0xb7a60130}, {0x13, 0xb8a61140}, {0x16, 0x90170110}, Patches currently in stable-queue which might be from kailang(a)realtek.com are queue-4.14/alsa-hda-realtek-fix-dell-aio-lineout-issue.patch

The rawmidi also allows to obtaining the information via ioctl of ctl API. It means that user can issue an ioctl to the rawmidi device even when it's being removed as long as the control device is present. Although the code has some protection via the global register_mutex, its range is limited to the search of the corresponding rawmidi object, and the mutex is already unlocked at accessing the rawmidi object. This may lead to a use-after-free. For avoiding it, this patch widens the application of register_mutex to the whole snd_rawmidi_info_select() function. We have another mutex per rawmidi object, but this operation isn't very hot path, so it shouldn't matter from the performance POV.

The commit f6f828513290 ("pstore: pass allocated memory region back to caller") changed the check of the return value from erst_read() in erst_reader() in the following way: if (len == -ENOENT) goto skip; - else if (len < 0) { - rc = -1; + else if (len < sizeof(*rcd)) { + rc = -EIO; goto out; This introduced another bug: since the comparison with sizeof() is cast to unsigned, a negative len value doesn't hit any longer. As a result, when an error is returned from erst_read(), the code falls through, and it may eventually lead to some weird thing like memory corruption.

[Linux-stable-mirror] Patch "PCI / PM: Force devices to D0 in pci_pm_thaw_noirq()" has been added to the 3.18-stable tree

This is a note to let you know that I've just added the patch titled PCI / PM: Force devices to D0 in pci_pm_thaw_noirq() to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: pci-pm-force-devices-to-d0-in-pci_pm_thaw_noirq.patch and it can be found in the queue-3.18 subdirectory.

Wysocki" <rafael.j.wysocki(a)intel.com> Date: Fri, 15 Dec 2017 03:07:18 +0100 Subject: PCI / PM: Force devices to D0 in pci_pm_thaw_noirq() From: Rafael J. Wysocki <rafael.j.wysocki(a)intel.com> commit 5839ee7389e893a31e4e3c9cf17b50d14103c902 upstream. It is incorrect to call pci_restore_state() for devices in low-power states (D1-D3), as that involves the restoration of MSI setup which requires MMIO to be operational and that is only the case in D0. However, pci_pm_thaw_noirq() may do that if the driver's "freeze" callbacks put the device into a low-power state, so fix it by making it force devices into D0 via pci_set_power_state() instead of trying to "update" their power state which is pointless.

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent node was prematurely freed, while the child node was leaked. Note that the CONFIG_OF compile guard can be removed as of_get_child_by_name() provides a !CONFIG_OF implementation which always fails.
