ALSA: usb-audio: Add quirk for Syntek STK1160

2016-10-27T10:07:19+00:00

The stk1160 chip needs QUIRK_AUDIO_ALIGN_TRANSFER. This patch resolves
the issue reported on the mailing list
(http://marc.info/?l=linux-sound&m=139223599126215&w=2) and also fixes
bug 180071 (https://bugzilla.kernel.org/show_bug.cgi?id=180071).

ALSA: seq: Fix time account regression

2016-10-25T14:00:46+00:00

The recent rewrite of the sequencer time accounting using timespec64
in the commit [3915bf294652: ALSA: seq_timer: use monotonic times
internally] introduced a bad regression.  Namely, the time reported
back doesn't increase but goes back and forth.

The culprit was obvious: the delta is stored to the result (cur_time =
delta), instead of adding the delta (cur_time += delta)!

Let's fix it.

ALSA: hda - Fix surround output pins for ASRock B150M mobo

2016-10-25T08:09:39+00:00

ASRock B150M Pro4/D3 mobo with ALC892 codec doesn't seem to provide
proper pins for the surround outputs, hence we need to specify the
pincfgs manually with a couple of other corrections.

ALSA: hda - Fix headset mic detection problem for two Dell laptops

2016-10-20T09:47:23+00:00

They uses the codec ALC255, and have the different pin cfg definition
from the ones in the existing pin quirk table. Now adding them into
the table to fix the problem.

ALSA: asihpi: fix kernel memory disclosure

2016-10-18T12:08:25+00:00

Some elements in hr are not cleared before being copied to user space,
leaking kernel heap memory to user space. For example, this happens in
the error handling code for the HPI_ADAPTER_DELETE case. Zero the memory
before it's copied.

ALSA: hda - Adding a new group of pin cfg into ALC295 pin quirk table

2016-10-18T09:52:46+00:00

We have a new Dell laptop model which uses ALC295, the pin definition
is different from the existing ones in the pin quirk table, to fix the
headset mic detection and mic mute led's problem, we need to add the
new pin defintion into the pin quirk table.

ALSA: hda - allow 40 bit DMA mask for NVidia devices

2016-10-18T09:20:17+00:00

Commit 49d9e77e72cf ("ALSA: hda - Fix system panic when DMA > 40 bits
for Nvidia audio controllers") simply disabled any DMA exceeding 32
bits for NVidia devices, even though they are capable of performing
DMA up to 40 bits. On some architectures (such as arm64), system memory
is not guaranteed to be 32-bit addressable by PCI devices, and so this
change prevents NVidia devices from working on platforms such as AMD
Seattle.

Since the original commit already mentioned that up to 40 bits of DMA
is supported, and given that the code has been updated in the meantime
to support a 40 bit DMA mask on other devices, revert commit 49d9e77e72cf
and explicitly set the DMA mask to 40 bits for NVidia devices.

ALSA: seq: fix passing wrong pointer in function call of compatibility layer

2016-10-12T18:09:36+00:00

This commit is a fix for Linux 4.9-rc1.

In former commit, a function call of compatibility layer for ALSA sequencer
core was obsoleted by an alternative. Although, the alternative gets a
pointer to kernel stack due to mis-programming. As a result, ALSA sequencer
core unexpectedly refers over kernel stack.
