[GIT PULL] sound fixes for 2.6.36

From: Takashi Iwai
Date: Sun Aug 15 2010 - 11:47:27 EST

Linus,

please pull sound fixes for v2.6.36 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for-linus

One regression fix of HD-audio in the previous update, a generic fix
for HDMI setup, AD8994 fixes and a few trivial changes.


Thanks!

Takashi

Andrea Gelmini (1):
sound: oss: sh_dac_audio.c removed duplicated #include

Dan Carpenter (1):
ALSA: sound/usb/format: silence uninitialized variable warnings

Mark Brown (4):
ASoC: Optimise DSP performance for WM8994
ASoC: Only tweak WM8994 chip configuration on devices up to rev D
MAINTAINERS: Make Wolfson entry also cover CODEC drivers
MAINTAINERS: Add Ian Lartey as comaintaner for Wolfson devices

Takashi Iwai (2):
ALSA: hda - Restrict PCM parameters per ELD information over HDMI
ALSA: hda - Fix dynamic ADC change working again
