ALSA: hda - disable dynamic clock gating on Broxton before reset

2016-01-29T13:00:41+00:00

On Broxton, to make sure the reset controller works properly,
MISCBDCGE bit (bit 6) in CGCTL (0x48) of PCI configuration space
need be cleared before reset and set back to 1 after reset.
Otherwise, it may prevent the CORB/RIRB logic from being reset.

ALSA: hda - Add new GPU codec ID 0x10de0083 to snd-hda

2016-01-29T06:28:17+00:00

Vendor ID 0x10de0083 is used by a yet-to-be-named GPU chip.

This chip also has the 2-ch audio swapping bug, so patch_nvhdmi is
appropriate here.

ALSA: dummy: Disable switching timer backend via sysfs

2016-01-28T07:13:54+00:00

ALSA dummy driver can switch the timer backend between system timer
and hrtimer via its hrtimer module option.  This can be also switched
dynamically via sysfs, but it may lead to a memory corruption when
switching is done while a PCM stream is running; the stream instance
for the newly switched timer method tries to access the memory that
was allocated by another timer method although the sizes differ.

As the simplest fix, this patch just disables the switch via sysfs by
dropping the writable bit.

ALSA: Add missing dependency on CONFIG_SND_TIMER

2016-01-27T06:10:38+00:00

Since the build of PCM timer may be disabled via Kconfig now, each
driver that provides a timer interface needs to set CONFIG_SND_TIMER
explicitly.  Otherwise it may get a build error due to missing
symbol.

ALSA: bebob: Use a signed return type for get_formation_index

2016-01-26T10:38:53+00:00

The return type "unsigned int" was used by the get_formation_index function
despite of the aspect that it will eventually return a negative	error code.
So, change to signed int and get index by reference in the parameters.

Done with the help of Coccinelle.

ALSA: usb-audio: Fix TEAC UD-501/UD-503/NT-503 usb delay

2016-01-26T05:58:57+00:00

TEAC UD-501/UD-503/NT-503 fail to switch properly between different
rate/format. Similar to 'Playback Design', this patch corrects the
invalid clock source error for TEAC products and avoids complete
freeze of the usb interface of 503 series.

ALSA: compress: Disable GET_CODEC_CAPS ioctl for some architectures

2016-01-25T19:27:33+00:00

Some architectures like PowerPC can handle the maximum struct size in
an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by
SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit.  This
problem was revealed recently by a powerpc change, as it's now treated
as a fatal build error.

This patch is a stop-gap for that: for architectures with less than 14
bit ioctl struct size, get rid of the handling of the relevant ioctl.
We should provide an alternative equivalent ioctl code later, but for
now just paper over it.  Luckily, the compress API hasn't been used on
such architectures, so the impact must be effectively zero.

ALSA: seq: Degrade the error message for too many opens

2016-01-25T10:52:23+00:00

ALSA OSS sequencer spews a kernel error message ("ALSA: seq_oss: too
many applications") when user-space tries to open more than the
limit.  This means that it can easily fill the log buffer.

Since it's merely a normal error, it's safe to suppress it via
pr_debug() instead.

ALSA: seq: Fix incorrect sanity check at snd_seq_oss_synth_cleanup()

2016-01-25T10:49:10+00:00

ALSA sequencer OSS emulation code has a sanity check for currently
opened devices, but there is a thinko there, eventually it spews
warnings and skips the operation wrongly like:
  WARNING: CPU: 1 PID: 7573 at sound/core/seq/oss/seq_oss_synth.c:311

Fix this off-by-one error.
