ALSA: hda - Add missing terminating entry to SND_HDA_PIN_QUIRK macro

2014-10-30T16:43:12+00:00

commit fb54a645b2739fb196446ffbbbe3f3589d117b55 upstream.

Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.

The result being that in some cases, the pin quirk would not be
applied correctly.

ALSA: hda - Fix inverted LED gpio setup for Lenovo Ideapad

2014-10-30T16:43:12+00:00

commit b1974f965a506c131b60cd3e483340884e831920 upstream.

We implemented in a wrong way for mute LED on Lenovo Ideapad; the bit
must be flipped.

ALSA: hda - hdmi: Fix missing ELD change event on plug/unplug

2014-10-30T16:43:12+00:00

commit 6acce400d9daf1353fbf497302670c90a3205e1d upstream.

The ELD ALSA control change event is sent by hdmi_present_sense() when
eld_changed is true.

Currently, it is only true when the ELD buffer contents have been
modified. However, the user-visible ELD controls also change to a
zero-length value and back when eld_valid is unset/set, and no event is
currently sent in such cases (such as when unplugging or replugging a
sink).

Fix the code to always set eld_changed if eld_valid value is changed,
and therefore to always send the change event when the user-visible
value changes.

ALSA: usb-audio: Add support for Steinberg UR22 USB interface

2014-10-30T16:43:12+00:00

commit f0b127fbfdc8756eba7437ab668f3169280bd358 upstream.

Adding support for Steinberg UR22 USB interface via quirks table patch

See Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1317244
Also see threads:
http://linux-audio.4202.n7.nabble.com/Support-for-Steinberg-UR22-Yamaha-USB-chipset-0499-1509-tc82888.html#a82917
http://www.steinberg.net/forums/viewtopic.php?t=62290

Tested by at least 4 people judging by the threads.
Did not test MIDI interface, but audio output and capture both are
functional. Built 3.17 kernel with this driver on Ubuntu 14.04 & tested with mpg123
Patch applied to 3.13 Ubuntu kernel works well enough for daily use.

ALSA: emu10k1: Fix deadlock in synth voice lookup

2014-10-30T16:43:11+00:00

commit 95926035b187cc9fee6fb61385b7da9c28123f74 upstream.

The emu10k1 voice allocator takes voice_lock spinlock.  When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice.  The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.

The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.

ALSA: bebob: Fix failure to detect source of clock for Terratec Phase 88

2014-10-30T16:43:11+00:00

commit 3f4032861cfbff0b9134bf94c5c92e2146d1f068 upstream.

This patch fixes a failure to open PCM device with -ENOSYS in
Terratec Phase 88.

Terratec Phase 88 has two Selector Function Blocks of AVC Audio subunit
to switch source of clock. One is to switch internal/external for the
source and another is to switch word/spdif for the external clock.

The IDs for these Selector Function Blocks are 9 and 8. But in current
implementation they're 0 and 0.

ASoC: Fix SSM2602 device identification

Another fix for v3.17, fixing device identification after the split out
of the I2C and SPI code.

ASoC: ssm2602: do not hardcode type to SSM2602

2014-09-30T12:27:19+00:00

The correct type (SSM2602/SSM2603/SSM2604) is passed down
from the ssm2602_spi_probe()/ssm2602_spi_probe() functions,
so use that instead of hardcoding it to SSM2602 in
ssm2602_probe().
