ALSA: oxygen: Xonar DG(X): modify DAC routing

2014-04-01T23:59:01+00:00

commit 1f91ecc14deea9461aca93273d78871ec4d98fcd upstream.

When selecting the audio output destinations (headphones, FP headphones,
multichannel output), unnecessary I2S channels are digitally muted to
avoid invalid signal levels on the other outputs.

ALSA: oxygen: Xonar DG(X): capture from I2S channel 1, not 2

2014-04-01T23:59:01+00:00

commit 3dd77654fb1d7f68b9739f3039bad8dbbc0739f8 upstream.

Actually CS4245 connected to the I2S channel 1 for
capture, not channel 2. Otherwise capturing and
playback does not work for CS4245.

ASoC: sta32x: Fix wrong enum for limiter2 release rate

2014-04-01T23:58:56+00:00

commit b3619b288b621e63f66908045f48495869a996a6 upstream.

There is a typo in the Limiter2 Release Rate control, a wrong enum for
Limiter1 is assigned.  It must point to Limiter2.

ASoC: wm8770: Fix wrong number of enum items

2014-04-01T23:58:54+00:00

commit 7a6c0a58dc824523966f212c76322d47c5b0e6fe upstream.

wm8770 codec driver defines ain_enum with a wrong number of items.

Use SOC_ENUM_DOUBLE_DECL() macro and it's automatically fixed.

ASoC: sta32x: Fix array access overflow

2014-04-01T23:58:54+00:00

commit 025c3fa9256d4c54506b7a29dc3befac54f5c68d upstream.

Preset EQ enum of sta32x codec driver declares too many number of
items and it may lead to the access over the actual array size.

Use SOC_ENUM_SINGLE_DECL() helper and it's automatically fixed.

ALSA: usb-audio: work around KEF X300A firmware bug

2014-04-01T23:58:53+00:00

commit 624aef494f86ed0c58056361c06347ad62b26806 upstream.

When the driver tries to access Function Unit 10, the KEF X300A
speakers' firmware apparently locks up, making even PCM streaming
impossible.  Work around this by ignoring this FU.

ALSA: hda/realtek - Avoid invalid COEFs for ALC271X

2014-04-01T23:58:48+00:00

commit d3c56568f43807135f2c2a09582a69f809f0d8b7 upstream.

We've seen often problems after suspend/resume on Acer Aspire One
AO725 with ALC271X codec as reported in kernel bugzilla, and it turned
out that some COEFs doesn't work and triggers the codec communication
stall.

Since these magic COEF setups are specific to ALC269VB for some PLL
configurations, the machine works even without these manual
adjustment.  So, let's simply avoid applying them for ALC271X.

ALSA: Enable CONFIG_ZONE_DMA for smaller PCI DMA masks

2014-04-01T23:58:42+00:00

commit 80ab8eae70e51d578ebbeb228e0f7a562471b8b7 upstream.

The PCI devices with DMA masks smaller than 32bit should enable
CONFIG_ZONE_DMA.  Since the recent change of page allocator, page
allocations via dma_alloc_coherent() with the limited DMA mask bits
may fail more frequently, ended up with no available buffers, when
CONFIG_ZONE_DMA isn't enabled.  With CONFIG_ZONE_DMA, the system has
much more chance to obtain such pages.

ASoC: adau1701: Fix ADAU1701_SEROCTL_WORD_LEN_16 constant

2014-04-01T23:58:42+00:00

commit e20970ada3f699c113fe64b04492af083d11a7d8 upstream.

The driver defines ADAU1701_SEROCTL_WORD_LEN_16 as 0x10 while it should be b10,
so 0x2. This patch fixes it.
