ALSA: hda - fix ELD memory leak

2011-11-26T17:08:36+00:00

Backported from commit b95d68b8179764e29558b75cec35ef4a6a98925b.

memset(eld) clears eld->proc_entry which will leak the struct
snd_info_entry when unloading module.

Fix it by
- memset only the fields before eld->eld_buffer
- set eld->eld_valid to true _after_ all eld fields have been filled

ALSA: hda - Fix the connection selection of ADCs on Cirrus codecs

2011-11-26T17:08:33+00:00

commit 05ee7964a470d29889ac48cc8274c1b5a1904a11 upstream.

spec->cur_adc isn't set until cs_capture_pcm_prepare() is called although
the driver tries to select the connection at init time and at auto-mic
switch.  This results in the access to the widget NID 0, which is
obviously invalid, also a wrong capture source.

This patch fixes the issue by issuing the connect-select verb conditionally
at appropriate places.

ALSA: usb-audio - Fix the missing volume quirks at delayed init

2011-11-21T22:35:21+00:00

commit dcaaf9f2c16b56f8bb316881fcd3f15c18fc71e7 upstream.

In the recent usb-audio driver, the initialization of volume ranges
may be delayed when the device doesn't respond well at the probing time.
But the volume quirks for certain devices are applied only in
mixer_ctl_feature_info() thus only at the very first probe and will be
missing when the volume range is initialized later.

This patch moves the volume quirk code to be always called from the
volume-range extraction (get_min_max()), so that the quirks are properly
applied in the later init time.

ALSA: usb-audio - Check the dB-range validity in the later read, too

2011-11-21T22:35:21+00:00

commit 9fcd0ab130579d9742538340edda3225f2b49a3e upstream.

When the initial check of dB-range failed due to the read error, try to
check again at the later read, too.  When an invalid dB range is found,
remove TLV flags and notify the mixer info change.

ASoC: Don't use wm8994->control_data in wm8994_readable_register()

2011-11-21T22:35:18+00:00

commit 8eeea521d9d0fa6afd62df8c6e6566ee946117fa upstream.

The field is no longer initialised so this will crash if running on
wm8958.

ALSA: hda - Don't add elements of other codecs to vmaster slave

2011-11-21T22:35:17+00:00

commit aeb4b88ec0a948efce8e3a23a8f964d3560a7308 upstream.

When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance.  But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus.  This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.

This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.

commit 2af8de8c39cf58e5a5e40a9d5d71332da98e6ba7 upstream.

Since there is no current software control for these they would otherwise
be left enabled, consuming power.

ASoC: Ensure WM8962 PLL registers are reset

2011-11-11T17:44:27+00:00

commit 4f4488abc97c1c27ff029f887944e6a6da1f5733 upstream.

The WM8962 has a separate software reset for the PLL registers. Ensure that
these are reset also on startup.
