ALSA: hda - Fix regression of monitor_present flag in eld proc file

2016-04-18T12:51:10+00:00

[ Upstream commit 023d8218ec0dfc30e11d4ec54f640e8f127d1fbe ]

The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier.  Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

ALSA: usb-audio: add Microsoft HD-5001 to quirks

2016-04-18T12:51:05+00:00

[ Upstream commit 0ef21100ae912f76ed89f76ecd894f4ffb3689c1 ]

The Microsoft HD-5001 webcam microphone does not support sample rate
reading as the HD-5000 one.
This results in dmesg errors and sound hanging with pulseaudio.

ALSA: hda - Fix forgotten HDMI monitor_present update

2016-04-18T12:51:04+00:00

[ Upstream commit bd48128539ab89986b24ad08ecd3e027dd1993a1 ]

We forgot to copy monitor_present value when updating the ELD
information.  This won't change the ELD retrieval and the jack
notification behavior, but appears only in the proc output.   In that
sense, it's no fatal error, but a bug is a bug is a bug.

ALSA: hda - Split ELD update code from hdmi_present_sense()

2016-04-18T12:51:04+00:00

[ Upstream commit e90247f9fceeebe5bdaac2d87e301e73bae9bc1f ]

This is a preliminary patch for the later change to support ELD/jack
handling with i915 audio component.  This splits the ELD update code
from hdmi_present_sense() so that it can be called from other places.

Just a code refactoring, no functional change.

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

2016-04-18T12:50:59+00:00

[ Upstream commit 447d6275f0c21f6cc97a88b3a0c601436a4cdf2a ]

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.

ALSA: usb-audio: Fix NULL dereference in create_fixed_stream_quirk()

2016-04-18T12:50:59+00:00

[ Upstream commit 0f886ca12765d20124bd06291c82951fd49a33be ]

create_fixed_stream_quirk() may cause a NULL-pointer dereference by
accessing the non-existing endpoint when a USB device with a malformed
USB descriptor is used.

This patch avoids it simply by adding a sanity check of bNumEndpoints
before the accesses.

ALSA: hda - Fix unconditional GPIO toggle via automute

2016-04-18T12:50:58+00:00

[ Upstream commit 1f7c6658962fa1260c1658d681bd6bb0c746b99a ]

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.

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.
