ALSA: usb-audio: Check for possible chip NULL pointer before clearing probing flag

2011-10-03T18:41:08+00:00

commit 61a6a108d15213f5ee06332e1e7766d3860e4453 upstream.

Before clearing the probing flag in the error exit path, check that the
chip pointer is not NULL.

ALSA: hda/realtek - Avoid bogus HP-pin assignment

2011-10-03T18:41:07+00:00

commit 5fe6e0151dbd969f5fbcd94d05c968b76d76952b upstream.

When the headphone pin is assigned as primary output to line_out_pins[],
the automatic HP-pin assignment by ASSID must be suppressed.  Otherwise
a wrong pin might be assigned to the headphone and breaks the auto-mute.

ASoC: ssm2602: Re-enable oscillator after suspend

2011-10-03T18:41:07+00:00

commit 9058020cd9ae3423d6fe7de591698dc96b6701aa upstream.

Currently the the internal oscillator is powered down when entering BIAS_OFF
state, but not re-enabled when going back to BIAS_STANDBY. As a result the
CODEC will stop working after suspend if the internal oscillator is used to
generate the sysclock signal. This patch fixes it by clearing the appropriate
bit in the power down register when the CODEC is re-enabled.

ASoC: omap-mcbsp: Do not attempt to change DAI sysclk if stream is active

2011-10-03T18:41:07+00:00

commit 34c869855a28af3c6031d29e2267b5a3cce0d67d upstream.

Attempt to change McBSP CLKS source while another stream is active is not
safe after commit d135865 ("OMAP: McBSP: implement functional clock
switching via clock framework") in 2.6.37.

CLKS parent clock switching using clock framework have to idle the McBSP
before switching and then activate it again. This short break can cause a
DMA transaction error to already running stream which halts and recovers
only by closing and restarting the stream.

This goes more fatal after commit e2fa61d ("OMAP3: l3: Introduce
l3-interconnect error handling driver") in 2.6.39 where l3 driver detects a
severe timeout error and does BUG_ON().

Fix this by not changing any configuration in omap_mcbsp_dai_set_dai_sysclk
if the McBSP is already active. This test should have been here just from
the beginning anyway.

ALSA: fm801: Gracefully handle failure of tuner auto-detect

2011-10-03T18:41:03+00:00

commit c37279b92aba2893578f61076cd2eef5c5fa0e99 upstream.

Commit 9676001559fce06e37c7dc230ab275f605556176
("ALSA: fm801: add error handling if auto-detect fails") seems to
break systems that were previously working without a tuner.

As a bonus, this should fix init and cleanup for the case where the
tuner is explicitly disabled.

ALSA: fm801: Fix double free in case of error in tuner detection

2011-10-03T18:41:03+00:00

commit 2ba34e43ba0469086d1ff81c13a9aa9070c1a0e1 upstream.

Commit 9676001559fce06e37c7dc230ab275f605556176
("ALSA: fm801: add error handling if auto-detect fails") added
incorrect error handling.

Once we have successfully called snd_device_new(), the cleanup
function fm801_free() will automatically be called by snd_card_free()
and we must *not* also call fm801_free() directly.

ALSA: usb-audio - clear chip->probing on error exit

2011-10-03T18:41:02+00:00

commit 362e4e49abe53e89d87455dfcd7c1bbaf08a839d upstream.

The Terratec Aureon 5.1 USB sound card support is broken since kernel
2.6.39.
2.6.39 introduced power management support for USB sound cards that added
a probing flag in struct snd_usb_audio.

During the probe of the card it gives following error message :

usb 7-2: new full speed USB device number 2 using uhci_hcd
cannot find UAC_HEADER
snd-usb-audio: probe of 7-2:1.3 failed with error -5
input: USB Audio as
/devices/pci0000:00/0000:00:1d.1/usb7/7-2/7-2:1.3/input/input6
generic-usb 0003:0CCD:0028.0001: input: USB HID v1.00 Device [USB Audio]
on usb-0000:00:1d.1-2/input3

I can not comment about that "cannot find UAC_HEADER" error, but until
2.6.38 the card worked anyway.
With 2.6.39 chip->probing remains 1 on error exit, and any later ioctl
stops in snd_usb_autoresume with -ENODEV.

ALSA: hda/realtek - Fix auto-mute with HP+LO configuration

2011-10-03T18:40:35+00:00

commit 8974bd51a77824d91010176f9a5da28513c2e1f5 upstream.

When the system has only the headphone and the line-out jacks without
speakers, the current auto-mute code doesn't work.  It's because the
spec->automute_lines flag is wrongly referred in update_speakers().
This flag must be meaningless when spec->automute_hp_lo isn't set, thus
they should be always coupled.

The patch fixes the problem and add a comment to indicate the
relationship briefly.
