ASoC: wm_adsp: Fix enum ctl accesses in a wrong type

2016-03-22T15:11:06+00:00

[ Upstream commit 15c665700bf6f4543f003ac0fbb1e9ec692e93f2 ]

The firmware ctls like "DSP1 Firmware" in wm_adsp codec driver are
enum, while the current driver accesses wrongly via
value.integer.value[].  They have to be via value.enumerated.item[]
instead.

ALSA: hda - Fix mic issues on Acer Aspire E1-472

2016-03-13T17:53:41+00:00

[ Upstream commit 02322ac9dee9aff8d8862e8d6660ebe102f492ea ]

This patch applies the microphone-related fix created for the Acer
Aspire E1-572 to the E1-472 as well, as it uses the same Realtek ALC282
CODEC and demonstrates the same issues.

This patch allows an external, headset microphone to be used and limits
the gain on the (quite noisy) internal microphone.

ALSA: seq: oss: Don't drain at closing a client

2016-03-11T14:45:25+00:00

[ Upstream commit 197b958c1e76a575d77038cc98b4bebc2134279f ]

The OSS sequencer client tries to drain the pending events at
releasing.  Unfortunately, as spotted by syzkaller fuzzer, this may
lead to an unkillable process state when the event has been queued at
the far future.  Since the process being released can't be signaled
any longer, it remains and waits for the echo-back event in that far
future.

Back to history, the draining feature was implemented at the time we
misinterpreted POSIX definition for blocking file operation.
Actually, such a behavior is superfluous at release, and we should
just release the device as is instead of keeping it up forever.

This patch just removes the draining call that may block the release
for too long time unexpectedly.

ALSA: usb-audio: Add a quirk for Plantronics DA45

2016-03-11T14:45:25+00:00

[ Upstream commit 17e2df4613be57d0fab68df749f6b8114e453152 ]

Plantronics DA45 does not support reading the sample rate which leads
to many lines of "cannot get freq at ep 0x4" and "cannot get freq at
ep 0x84". This patch adds the USB ID of the DA45 to quirks.c and
avoids those error messages.

ALSA: hdsp: Fix wrong boolean ctl value accesses

[ Upstream commit eab3c4db193f5fcccf70e884de9a922ca2c63d80 ]

snd-hdsp driver accesses enum item values (int) instead of boolean
values (long) wrongly for some ctl elements.  This patch fixes them.

ALSA: hdspm: Fix zero-division

2016-03-11T14:45:24+00:00

[ Upstream commit c1099c3294c2344110085a38c50e478a5992b368 ]

HDSPM driver contains a code issuing zero-division potentially in
system sample rate ctl code.  This patch fixes it by not processing
a zero or invalid rate value as a divisor, as well as excluding the
invalid value to be passed via the given ctl element.

ALSA: timer: Fix ioctls for X32 ABI

2016-03-11T14:45:23+00:00

[ Upstream commit b24e7ad1fdc22177eb3e51584e1cfcb45d818488 ]

X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes
incompatible with IA32.  This results in NOTTY error when the ioctl is
issued.

Meanwhile, this struct in X32 is essentially identical with the one in
X86-64, so we can just bypassing to the existing code for this
specific compat ioctl.
