ASoC: Fixes for v4.13

A couple of fixes, one for a regression in simple-card introduced during
the merge window that was only reported this week and another for a
regression in registration of ACPI GPIOs.

ASoC: simple_card_utils: fix fallback when "label" property isn't present

2017-08-30T17:41:38+00:00

snd_soc_of_parse_card_name() doesn't return an error if the requested
property isn't present, but silently fails to fill the card name. This can
not be changed, as it is a backwards compatibility measure itself.

We can not rely on the return value of this function alone, but must check
if the card name has been filled sucessfully when deciding to skip the
fallback path, which is in place for existing users.

ALSA: pcm: Fix power lock unbalance via OSS emulation

2017-08-30T13:10:12+00:00

PCM OSS emulation issues the drain ioctl without power lock.  It used
to work in the earlier kernels as the power lock was taken inside
snd_pcm_drain() itself.  But since 68b4acd32249 ("ALSA: pcm: Apply
power lock globally to common ioctls"), the power lock is taken
outside the function.  Due to that change, the call via OSS emulation
leads to the unbalanced power lock, thus it deadlocks.

As a quick fix, just take the power lock before snd_pcm_drain() call
for OSS emulation path.  A better cleanup will follow later.

ASoC: rt5677: Reintroduce I2C device IDs

2017-08-24T16:04:29+00:00

Not all devices with ACPI and this combination of sound devices will
have the required information provided via ACPI.  Reintroduce the I2C
device ID to restore sound functionality on on the Chromebook 'Samus'
model.

[ More background note:
 the commit a36afb0ab648 ("ASoC: rt5677: Introduce proper table...")
 moved the i2c ID probed via ACPI ("RT5677CE:00") to a proper
 acpi_device_id table.  Although the action itself is correct per se,
 the overseen issue is the reference id->driver_data at
 rt5677_i2c_probe() for retrieving the corresponding chip model for
 the given id.  Since id=NULL is passed for ACPI matching case, we get
 an Oops now.

 We already have queued more fixes for 4.14 and they already address
 the issue, but they are bigger changes that aren't preferable for the
 late 4.13-rc stage.  So, this patch just papers over the bug as a
 once-off quick fix for a particular ACPI matching.  -- tiwai ]

ALSA: hda - Add stereo mic quirk for Lenovo G50-70 (17aa:3978)

2017-08-23T07:30:17+00:00

Lenovo G50-70 (17aa:3978) with Conexant codec chip requires the
similar workaround for the inverted stereo dmic like other Lenovo
models.

ALSA: core: Fix unexpected error at replacing user TLV

2017-08-22T13:43:40+00:00

When user tries to replace the user-defined control TLV, the kernel
checks the change of its content via memcmp().  The problem is that
the kernel passes the return value from memcmp() as is.  memcmp()
gives a non-zero negative value depending on the comparison result,
and this shall be recognized as an error code.

The patch covers that corner-case, return 1 properly for the changed
TLV.

ASoC: rt5670: Fix GPIO headset detection regression

2017-08-22T12:48:34+00:00

RT5670 codec driver and its machine driver for Intel CHT assume the
implicit GPIO mapping on the index 0 while BIOS on most devices don't
provide it.  The recent commit f10e4bf6632b ("gpio: acpi: Even more
tighten up ACPI GPIO lookups") restricts such cases and it resulted in
a regression where the headset jack setup fails like:

  rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2
  rt5670 i2c-10EC5672:00: Adding jack GPIO failed

For fixing this, we need to provide the GPIO mapping explicitly in the
machine driver.  Also this patch corrects the string to be passed to
gpiolib to match with the pre-given mapping, too.

ALSA: usb-audio: Add delay quirk for H650e/Jabra 550a USB headsets

2017-08-22T09:15:15+00:00

These headsets reports a lot of: cannot set freq 44100 to ep 0x81

Zoom R16/24. Add both headsets to the Zoom R16/24 quirk for
a 1 ms delay between control msgs.

ALSA: firewire-motu: destroy stream data surely at failure of card initialization

2017-08-20T07:40:45+00:00

When failing sound card registration after initializing stream data, this
module leaves allocated data in stream data. This commit fixes the bug.
