ALSA: hda - Fix pincfg at resume on Lenovo T470 dock

2018-03-11T15:21:28+00:00

commit 71db96ddfa72671bd43cacdcc99ca178d90ba267 upstream.

We've added a quirk to enable the recent Lenovo dock support, where it
overwrites the pin configs of NID 0x17 and 19, not only updating the
pin config cache.  It works right after the boot, but the problem is
that the pin configs are occasionally cleared when the machine goes to
PM.  Meanwhile the quirk writes the pin configs only at the pre-probe,
so this won't be applied any longer.

For addressing that issue, this patch moves the code to overwrite the
pin configs into HDA_FIXUP_ACT_INIT section so that it's always
applied at both probe and resume time.

ALSA: hda: Add a power_save blacklist

2018-03-11T15:21:28+00:00

commit 1ba8f9d308174e647b864c36209b4d7934d99888 upstream.

On some boards setting power_save to a non 0 value leads to clicking /
popping sounds when ever we enter/leave powersaving mode. Ideally we would
figure out how to avoid these sounds, but that is not always feasible.

This commit adds a blacklist for devices where powersaving is known to
cause problems and disables it on these devices.

Note I tried to put this blacklist in userspace first:
https://github.com/systemd/systemd/pull/8128

But the systemd maintainers rightfully pointed out that it would be
impossible to then later remove entries once we actually find a way to
make power-saving work on listed boards without issues. Having this list
in the kernel will allow removal of the blacklist entry in the same commit
which fixes the clicks / plops.

The blacklist only applies to the default power_save module-option value,
if a user explicitly sets the module-option then the blacklist is not
used.

[ added an ifdef CONFIG_PM for the build error -- tiwai]

commit 240a8af929c7c57dcde28682725b29cf8474e8e5 upstream.

The capture interface doesn't work and the playback interface only

ASoC: nau8825: fix issue that pop noise when start capture

2018-03-03T09:23:22+00:00

[ Upstream commit d070f7c703ef26e3db613f24206823f916272fc6 ]

In skylake platform, we hear a loud pop noise(0 dB) at start of
audio capture power up sequence. This patch removes the pop noise
from the recording by adding a delay before enabling ADC.

ALSA: hda/ca0132 - fix possible NULL pointer use

2018-02-25T10:05:53+00:00

commit 46a049dae771b95e77ac6c823330f4a60f600236 upstream.

gcc-7 caught what it considers a NULL pointer dereference:

sound/pci/hda/patch_ca0132.c: In function 'dspio_scp.constprop':
sound/pci/hda/patch_ca0132.c:1487:4: error: argument 1 null where non-null expected [-Werror=nonnull]

This is plausible from looking at the function, as we compare 'reply'
to NULL earlier in it. I have not tried to analyze if there are constraints
that make it impossible to hit the bug, but adding another NULL check in
the end kills the warning and makes the function more robust.

ASoC: ux500: add MODULE_LICENSE tag

2018-02-25T10:05:44+00:00

commit 1783c9d7cb7bc3181b9271665959b87280d98d8e upstream.

This adds MODULE_LICENSE/AUTHOR/DESCRIPTION tags to the ux500
platform drivers, to avoid these build warnings:

WARNING: modpost: missing MODULE_LICENSE() in sound/soc/ux500/snd-soc-ux500-plat-dma.o
WARNING: modpost: missing MODULE_LICENSE() in sound/soc/ux500/snd-soc-ux500-mach-mop500.o

The company no longer exists, so the email addresses of the authors
don't work any more, but I've added them anyway for consistency.

ALSA: seq: Fix racy pool initializations

2018-02-22T14:43:51+00:00

commit d15d662e89fc667b90cd294b0eb45694e33144da upstream.

ALSA sequencer core initializes the event pool on demand by invoking
snd_seq_pool_init() when the first write happens and the pool is
empty.  Meanwhile user can reset the pool size manually via ioctl
concurrently, and this may lead to UAF or out-of-bound accesses since
the function tries to vmalloc / vfree the buffer.

A simple fix is to just wrap the snd_seq_pool_init() call with the
recently introduced client->ioctl_mutex; as the calls for
snd_seq_pool_init() from other side are always protected with this
mutex, we can avoid the race.

ALSA: hda/realtek: PCI quirk for Fujitsu U7x7

2018-02-22T14:43:50+00:00

commit fdcc968a3b290407bcba9d4c90e2fba6d8d928f1 upstream.

These laptops have a combined jack to attach headsets, the U727 on
the left, the U757 on the right, but a headsets microphone doesn't
work. Using hdajacksensetest I found that pin 0x19 changed the
present state when plugging the headset, in addition to 0x21, but
didn't have the correct configuration (shown as "Not connected").

So this sets the configuration to the same values as the headphone
pin 0x21 except for the device type microphone, which makes it
work correctly. With the patch the configured pins for U727 are

Pin 0x12 (Internal Mic, Mobile-In): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x19 (Black Mic, Left side): present = No
Pin 0x1d (Internal Aux): present = No
Pin 0x21 (Black Headphone, Left side): present = No
