ALSA: hda/realtek: Enable HP amp and mute LED on HP Folio 9480m [v3]

2016-08-22T16:23:25+00:00

[ Upstream commit 98973f2f083a5ec580da8bbb685e6baa93613546 ]

This laptop needs GPIO4 pulled high to enable the headphone amplifier,
and has a mute LED on GPIO3. I modelled the patch on the existing
GPIO4 code which pulls the line low for the same purpose; this time,
the HP amp line is pulled high.

v2: Disable the headphone amplifier when no headphone is connected.
    Don't disable power savings to preserve the LED state.

v3: Remove headset-specific hooks and code; this is just a headphone.

ALSA: hda: add AMD Stoney PCI ID with proper driver caps

2016-08-08T01:49:03+00:00

[ Upstream commit d716fb03f76411fc7e138692e33b749cada5c094 ]

This allows the device to correctly show up as ATI HDMI
rather than a generic one and allows the driver to use
the available caps.

ALSA: hda - fix use-after-free after module unload

2016-08-08T01:47:34+00:00

[ Upstream commit ab58d8cc870ef3f0771c197700441936898d1f1d ]

register_vga_switcheroo() sets the PM ops from the hda structure which
is freed later in azx_free. Make sure that these ops are cleared.

Caught by KASAN, initially noticed due to a general protection fault.

ALSA: ctl: Stop notification after disconnection

2016-08-08T01:45:07+00:00

[ Upstream commit f388cdcdd160687c6650833f286b9c89c50960ff ]

snd_ctl_remove() has a notification for the removal event.  It's
superfluous when done during the device got disconnected.  Although
the notification itself is mostly harmless, it may potentially be
harmful, and should be suppressed.  Actually some components PCM may
free ctl elements during the disconnect or free callbacks, thus it's
no theoretical issue.

This patch adds the check of card->shutdown flag for avoiding
unnecessary notifications after (or during) the disconnect.

ALSA: hda/realtek - add new pin definition in alc225 pin quirk table

2016-08-08T01:45:01+00:00

[ Upstream commit 8a132099f080d7384bb6ab4cc168f76cb4b47d08 ]

We have some Dell laptops which can't detect headset mic, the machines
use the codec ALC225, they have some new pin configuration values,
after adding them in the alc225 pin quirk table, they work well.

ALSA: timer: Fix negative queue usage by racy accesses

2016-07-19T22:20:25+00:00

[ Upstream commit 3fa6993fef634e05d200d141a85df0b044572364 ]

The user timer tu->qused counter may go to a negative value when
multiple concurrent reads are performed since both the check and the
decrement of tu->qused are done in two individual locked contexts.
This results in bogus read outs, and the endless loop in the
user-space side.

The fix is to move the decrement of the tu->qused counter into the
same spinlock context as the zero-check of the counter.

ALSA: au88x0: Fix calculation in vortex_wtdma_bufshift()

2016-07-19T22:20:12+00:00

[ Upstream commit 62db7152c924e4c060e42b34a69cd39658e8a0dc ]

vortex_wtdma_bufshift() function does calculate the page index
wrongly, first masking then shift, which always results in zero.
The proper computation is to first shift, then mask.

ALSA: echoaudio: Fix memory allocation

2016-07-19T22:20:01+00:00

[ Upstream commit 9c6795a9b3cbb56a9fbfaf43909c5c22999ba317 ]

'commpage_bak' is allocated with 'sizeof(struct echoaudio)' bytes.
We then copy 'sizeof(struct comm_page)' bytes in it.
On my system, smatch complains because one is 2960 and the other is 3072.

This would result in memory corruption or a oops.
