2018-07-18T10:17:46+00:00

The PCI SSID 1558:95e1 needs the same quirk for other Clevo P950
models, too.  Otherwise no sound comes out of speakers.

ALSA: rawmidi: Change resized buffers atomically

2018-07-17T15:33:17+00:00

The SNDRV_RAWMIDI_IOCTL_PARAMS ioctl may resize the buffers and the
current code is racy.  For example, the sequencer client may write to
buffer while it being resized.

As a simple workaround, let's switch to the resized buffer inside the
stream runtime lock.

ALC294_FIXUP_LENOVO_MIC_LOCATION, and they have the same pin cfg as
the machine with subsystem id:0x17aa3136, now use the pincfg table
to apply the fixup for them.

ALSA: hda - Handle pm failure during hotplug

2018-07-02T14:14:05+00:00

Obtaining the runtime pm wakeref can fail, especially in a hotplug
scenario where i915.ko has been unloaded. If we do not catch the
failure, we end up with an unbalanced pm.

v2 additions by tiwai:
hdmi_present_sense() checks the return value and handle only a
negative error case and bails out only if it's really still suspended.
Also, snd_hda_power_down() is called at the error path so that the
refcount is balanced.

Along with it, the spec->pcm_lock is taken outside
hdmi_present_sense() in the caller side, so that it won't cause
deadlock at reentrace via runtime resume.

v3 fix by tiwai:
Missing linux/pm_runtime.h is included.

ALSA: seq: Fix UBSAN warning at SNDRV_SEQ_IOCTL_QUERY_NEXT_CLIENT ioctl

2018-06-25T09:18:04+00:00

The kernel may spew a WARNING with UBSAN undefined behavior at
handling ALSA sequencer ioctl SNDRV_SEQ_IOCTL_QUERY_NEXT_CLIENT:

UBSAN: Undefined behaviour in sound/core/seq/seq_clientmgr.c:2007:14
signed integer overflow:

It happens only when INT_MAX is passed there, as we're incrementing it
unconditionally.  So the fix is trivial, check the value with
INT_MAX.  Although the bug itself is fairly harmless, it's better to
fix it so that fuzzers won't hit this again later.
