ASoC: 88pm860x: array overflow in snd_soc_put_volsw_2r_st()

2013-10-13T21:51:07+00:00

commit d967967e8d1116fb38bad25e58714b5dddd03cca upstream.

This is called from snd_ctl_elem_write() with user supplied data so we
need to add some bounds checking.

ASoC: max98095: a couple array underflows

2013-10-13T21:51:07+00:00

commit f8d7b13e14357ed19d2ca2799539600418dc3939 upstream.

The ->put() function are called from snd_ctl_elem_write() with user
supplied data.  The limit checks here could underflow leading to a
crash.

ALSA: hda - Add Toshiba Satellite C870 to MSI blacklist

2013-09-26T23:52:47+00:00

commit 83f72151352791836a1b9c1542614cc9bf71ac61 upstream.

Toshiba Satellite C870 shows interrupt problems occasionally when
certain mixer controls like "Mic Switch" is toggled.  This seems
worked around by not using MSI.

ASoC: wm8960: Fix PLL register writes

2013-09-26T23:52:47+00:00

commit 85fa532b6ef920b32598df86b194571a7059a77c upstream.

Bit 9 of PLL2,3 and 4 is reserved as '0'. The 24bit fractional part
should be split across each register in 8bit chunks.

ALSA: opti9xx: Fix conflicting driver object name

2013-09-08T04:49:32+00:00

commit fb615499f0ad28ed74201c1cdfddf9e64e205424 upstream.

The recent commit to delay the release of kobject triggered NULL
dereferences of opti9xx drivers.  The cause is that all
snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers
register the PnP card driver with the very same name, and also
snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with
the same name, too.  When these drivers are built in, quick
"register-release-and-re-register" actions occur, and this results in
Oops because of the same name is assigned to the kobject.

The fix is simply to assign individual names.  As a bonus, by using
KBUILD_MODNAME, the patch reduces more lines than it adds.

The fix is based on the suggestion by Russell King.

ASoC: max98088 - fix element type of the register cache.

2013-08-04T07:43:30+00:00

commit cb6f66a2d278e57a6c9d8fb59bd9ebd8ab3965c2 upstream.

The registers of max98088 are 8 bits, not 16 bits. This bug causes the
contents of registers to be overwritten with bad values when the codec
is suspended and then resumed.

ALSA: usb-audio: 6fire: return correct XRUN indication

commit be2f93a4c4981b3646b6f98f477154411b8516cb upstream.

Return SNDRV_PCM_POS_XRUN (snd_pcm_uframes_t) instead of
SNDRV_PCM_STATE_XRUN (snd_pcm_state_t) from the pointer
function of 6fire, as expected by snd_pcm_update_hw_ptr0().

ASoC: sglt5000: Fix SGTL5000_PLL_FRAC_DIV_MASK

commit 5c78dfe87ea04b501ee000a7f03b9432ac9d008c upstream.

SGTL5000_PLL_FRAC_DIV_MASK is used to mask bits 0-10 (11 bits in total) of
register CHIP_PLL_CTRL, so fix the mask to accomodate all this bit range.

ALSA: usb-audio: work around Android accessory firmware bug

2013-06-27T17:34:31+00:00

commit 342cda29343a6272c630f94ed56810a76740251b upstream.

When the Android firmware enables the audio interfaces in accessory
mode, it always declares in the control interface's baInterfaceNr array
that interfaces 0 and 1 belong to the audio function.  However, the
accessory interface itself, if also enabled, already is at index 0 and
shifts the actual audio interface numbers to 1 and 2, which prevents the
PCM streaming interface from being seen by the host driver.

To get the PCM interface interface to work, detect when the descriptors
point to the (for this driver useless) accessory interface, and redirect
to the correct one.
