ASoC: sun4i-codec: return error code instead of NULL when create_card fails

2016-11-18T09:51:52+00:00

commit 85915b63ad8b796848f431b66c9ba5e356e722e5 upstream.

When sun4i_codec_create_card fails, we do not assign a proper error
code to the return value. The return value would be 0 from the previous
function call, or we would have bailed out sooner. This would confuse
the driver core into thinking the device probe succeeded, when in fact
it didn't, leaving various devres based resources lingering.

Make the create_card function pass back a meaningful error code, and
assign it to the return value.

ASoC: Intel: Skylake: Always acquire runtime pm ref on unload

2016-11-18T09:51:52+00:00

commit 6d13f62d931ba638e54ba56f3a7dd3080ffb485a upstream.

skl_probe() releases a runtime pm ref unconditionally wheras
skl_remove() acquires one only if the device is wakeup capable.
Thus if the device is not wakeup capable, unloading and reloading
the module will result in the refcount being decreased below 0.
Fix it.

ASoC: cs4270: fix DAPM stream name mismatch

2016-11-18T09:51:43+00:00

commit aa5f920993bda2095952177eea79bc8e58ae6065 upstream.

Mismatching stream names in DAPM route and widget definitions are
causing compilation errors. Fixing these names allows the cs4270
driver to compile and function.

ALSA: info: Limit the proc text input size

2016-11-18T09:51:43+00:00

commit 027a9fe6835620422b6713892175716f3613dd9d upstream.

The ALSA proc handler allows currently the write in the unlimited size
until kmalloc() fails.  But basically the write is supposed to be only
for small inputs, mostly for one line inputs, and we don't have to
handle too large sizes at all.  Since the kmalloc error results in the
kernel warning, it's better to limit the size beforehand.

This patch adds the limit of 16kB, which must be large enough for the
currently existing code.

ALSA: info: Return error for invalid read/write

2016-11-18T09:51:43+00:00

commit 6809cd682b82dfff47943850d1a8c714f971b5ca upstream.

Currently the ALSA proc handler allows read or write even if the proc
file were write-only or read-only.  It's mostly harmless, does thing
but allocating memory and ignores the input/output.  But it doesn't
tell user about the invalid use, and it's confusing and inconsistent
in comparison with other proc files.

This patch adds some sanity checks and let the proc handler returning
an -EIO error when the invalid read/write is performed.

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

They uses the codec ALC255, and have the different pin cfg definition

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

commit 1a3f099101b85cc93d864eb030d97e7725c72ea7 upstream.

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.

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

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

2016-11-10T15:38:47+00:00

commit 3ab7511eafdd5c4f40d2832f09554478dfbea170 upstream.

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 time account regression

2016-11-10T15:38:47+00:00

commit 9b50898ad96c793a8f7cde9d8f281596d752a7dd upstream.

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.
