ALSA: hda - fix typo in proc output

2013-04-12T16:18:08+00:00

commit aeb3a97222832e5457c4b72d72235098ce4bfe8d upstream.

Rename "Digitial In" to "Digital In". This function is only used for
proc output, so should not cause any problems to change.

ALSA: hda - bug fix on return value when getting HDMI ELD info

2013-04-12T16:18:08+00:00

commit 2ef5692efad330b67a234e2c49edad38538751e7 upstream.

In function snd_hdmi_get_eld(), the variable 'ret' should be initialized to 0.
Otherwise it will be returned uninitialized as non-zero after ELD info is got
successfully. Thus hdmi_present_sense() will always assume ELD info is invalid
by mistake, and /proc file system cannot show the proper ELD info.

ASoC: dma-sh7760: Fix compile error

2013-04-12T16:18:08+00:00

commit 417a1178f1bf3cdc606376b3ded3a22489fbb3eb upstream.

The dma-sh7760 currently fails with the following compile error:
	sound/soc/sh/dma-sh7760.c:346:2: error: unknown field 'pcm_ops' specified in initializer
	sound/soc/sh/dma-sh7760.c:346:2: warning: initialization from incompatible pointer type

	sound/soc/sh/dma-sh7760.c:347:2: warning: initialization makes integer from pointer without a cast
	sound/soc/sh/dma-sh7760.c:348:2: error: unknown field 'pcm_free' specified in initializer
	sound/soc/sh/dma-sh7760.c:348:2: warning: initialization from incompatible pointer type
	sound/soc/sh/dma-sh7760.c: In function 'sh7760_soc_platform_probe':
	sound/soc/sh/dma-sh7760.c:353:2: warning: passing argument 2 of 'snd_soc_register_platform' from incompatible pointer type
	include/sound/soc.h:368:5: note: expected 'struct snd_soc_platform_driver *' but argument is of type 'struct snd_soc_platform *'

This is due the misnaming of the snd_soc_platform_driver type name and 'ops'
field. The issue was introduced in commit f0fba2a("ASoC: multi-component - ASoC
Multi-Component Support").

ALSA: snd-usb: mixer: ignore -EINVAL in snd_usb_mixer_controls()

2013-03-28T19:06:02+00:00

commit 83ea5d18d74f032a760fecde78c0210f66f7f70c upstream.

Creation of individual mixer controls may fail, but that shouldn't cause
the entire mixer creation to fail. Even worse, if the mixer creation
fails, that will error out the entire device probing.

All the functions called by parse_audio_unit() should return -EINVAL if
they find descriptors that are unsupported or believed to be malformed,
so we can safely handle this error code as a non-fatal condition in
snd_usb_mixer_controls().

That fixes a long standing bug which is commonly worked around by
adding quirks which make the driver ignore entire interfaces. Some of
them might now be unnecessary.

ALSA: snd-usb: mixer: propagate errors up the call chain

2013-03-28T19:06:01+00:00

commit 4d7b86c98e445b075c2c4c3757eb6d3d6efbe72e upstream.

In check_input_term() and parse_audio_feature_unit(), propagate the
error value that has been returned by a failing function instead of
-EINVAL. That helps cleaning up the error pathes in the mixer.

ALSA: seq: Fix missing error handling in snd_seq_timer_open()

2013-03-20T19:58:52+00:00

commit 66efdc71d95887b652a742a5dae51fa834d71465 upstream.

snd_seq_timer_open() didn't catch the whole error path but let through
if the timer id is a slave.  This may lead to Oops by accessing the
uninitialized pointer.

ALSA: vmaster: Fix slave change notification

2013-03-14T18:32:05+00:00

commit 2069d483b39a603a5f3428a19d3b4ac89aa97f48 upstream.

When a value of a vmaster slave control is changed, the ctl change
notification is sometimes ignored.  This happens when the master
control overrides, e.g. when the corresponding master control is
muted.  The reason is that slave_put() returns the value of the actual
slave put callback, and it doesn't reflect the virtual slave value
change.

This patch fixes the function just to return 1 whenever a slave value
is changed.
