ALSA: hda - Fix unconditional GPIO toggle via automute

2016-04-12T16:08:53+00:00

commit 1f7c6658962fa1260c1658d681bd6bb0c746b99a upstream.

Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically
depending on the jack plug state.  This works fine for the auto-mute
mode where the speaker gets muted upon the HP jack plug.   OTOH, when
the auto-mute mode is off, this turns off the EAPD unexpectedly
depending on the jack state, which results in the silent speaker
output.

This patch fixes the silent speaker output issue by setting GPIO bits
constantly when the auto-mute mode is off.

ALSA: hda - fix the mic mute button and led problem for a Lenovo AIO

2016-04-12T16:08:52+00:00

commit 6ef2f68fa38bf415830f67903d87180d933e0f47 upstream.

This Lenovo ThinkCentre AIO also uses Line2 as mic mute button and
uses GPIO2 to control the mic mute led, so applying this quirk can
make both the button and led work.

ALSA: hda - Don't handle ELD notify from invalid port

2016-04-12T16:08:52+00:00

commit 4f8e4f3537cafc4de128e6bfdf83baa78bc60eb1 upstream.

The current Intel HDMI codec driver supports only three fixed ports
from port B to port D.  However, i915 driver may assign a DP on other
ports, e.g. port A, when no eDP is used.  This incompatibility is
caught later at pin_nid_to_pin_index() and results in a warning
message like "HDMI: pin nid 4 not registered" at each time.

This patch filters out such invalid events beforehand, so that the
kernel won't be too grumbling.

ALSA: intel8x0: Add clock quirk entry for AD1981B on IBM ThinkPad X41.

2016-04-12T16:08:52+00:00

commit 4061db03dd71d195b9973ee466f6ed32f6a3fc16 upstream.

The clock measurement on the AC'97 audio card found in the IBM ThinkPad X41
will often fail, so add a quirk entry to fix it.

ALSA: pcm: Avoid "BUG:" string for warnings again

2016-04-12T16:08:52+00:00

commit 0ab1ace856205d10cbc1924b2d931c01ffd216a6 upstream.

The commit [d507941beb1e: ALSA: pcm: Correct PCM BUG error message]
made the warning prefix back to "BUG:" due to its previous wrong
prefix.  But a kernel message containing "BUG:" seems taken as an Oops
message wrongly by some brain-dead daemons, and it annoys users in the
end.  Instead of teaching daemons, change the string again to a more
reasonable one.

ALSA: hda - Apply reboot D3 fix for CX20724 codec, too

2016-04-12T16:08:52+00:00

commit 56dc66ff1c6d71f9a38c4a7c000b72b921fe4c89 upstream.

Just like CX20722, CX7024 codec also requires the power down at reboot
in order to reduce the noise at reboot/shutdown.

ALSA: usb-audio: Fix double-free in error paths after snd_usb_add_audio_stream() call

2016-04-12T16:08:44+00:00

commit 836b34a935abc91e13e63053d0a83b24dfb5ea78 upstream.

create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and
create_uaxx_quirk() functions allocate the audioformat object by themselves
and free it upon error before returning. However, once the object is linked
to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be
double-freed, eventually resulting in a memory corruption.

This patch fixes these failures in the error paths by unlinking the audioformat
object before freeing it.

Based on a patch by Takashi Iwai 

[Note for stable backports:
 this patch requires the commit 902eb7fd1e4a ('ALSA: usb-audio: Minor
 code cleanup in create_fixed_stream_quirk()')]

ALSA: usb-audio: Add sanity checks for endpoint accesses

2016-04-12T16:08:43+00:00

commit 447d6275f0c21f6cc97a88b3a0c601436a4cdf2a upstream.

Add some sanity check codes before actually accessing the endpoint via
get_endpoint() in order to avoid the invalid access through a
malformed USB descriptor.  Mostly just checking bNumEndpoints, but in
one place (snd_microii_spdif_default_get()), the validity of iface and
altsetting index is checked as well.
