ASoC: wm8962: Turn on regcache_cache_only before disabling regulator

2013-12-04T18:50:13+00:00

commit 50bfcf2df2fadf77e143d6099150e6fa7ef4d78c upstream.

It's safer to turn on regcache_cache_only before disabling regulator since
the driver will turn off the regcache_cache_only after enabling regulator.

If we remain cache_only false, some command like 'amixer cset' would get
failure if being run before wm8962_resume().

ASoC: ak4642: prevent un-necessary changes to SG_SL1

2013-12-04T18:50:13+00:00

commit 7b5bfb82882b9b1c8423ce0ed6852ca3762d967a upstream.

If you record the sound during playback,
the playback sound becomes silent.
Modify so that the codec driver does not clear
SG_SL1::DACL bit which is controlled under widget

ALSA: msnd: Avoid duplicated driver name

2013-11-29T18:50:34+00:00

commit 092f9cd16aac7d054af1755c945f37c1b33399e6 upstream.

msnd_pinnacle.c is used for both snd-msnd-pinnacle and
snd-msnd-classic drivers, and both should have different driver
names.  Using the same driver name results in the sysfs warning for
duplicated entries like
 kobject: 'msnd-pinnacle.7' (cec33408): kobject_release, parent   (null) (delayed)
 kobject: 'msnd-pinnacle' (cecd4980): kobject_release, parent cf3ad9b0 (delayed)

ALSA: 6fire: Fix probe of multiple cards

2013-11-29T18:50:34+00:00

commit 9b389a8a022110b4bc055a19b888283544d9eba6 upstream.

The probe code of snd-usb-6fire driver overrides the devices[] pointer
wrongly without checking whether it's already occupied or not.  This
would screw up the device disconnection later.

ALSA: hda - Move one-time init codes from generic_hdmi_init()

2013-11-20T18:43:18+00:00

commit 8b8d654b55648561287bd8baca0f75f964a17038 upstream.

The codes to initialize work struct or create a proc interface should
be called only once and never although it's called many times through
the init callback.  Move that stuff into patch_generic_hdmi() so that
it's called only once.

---[ end trace cb3d9bdb8dfefb3c ]---

This is provoked when the ASoC front end is open along with its backend,
(which causes the backend to have a runtime assigned to it) and then the
SNDRV_CTL_IOCTL_PCM_INFO is requested for the (visible) backend device.

Resolve this by ensuring that ASoC internal backend devices are not
visible to userspace, just as the commentry for snd_pcm_new_internal()
says it should be.
