Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6 

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6:
  ALSA: sound/usb/format: silence uninitialized variable warnings
  MAINTAINERS: Add Ian Lartey as comaintaner for Wolfson devices
  MAINTAINERS: Make Wolfson entry also cover CODEC drivers
  ASoC: Only tweak WM8994 chip configuration on devices up to rev D
  ASoC: Optimise DSP performance for WM8994
  ALSA: hda - Fix dynamic ADC change working again
  ALSA: hda - Restrict PCM parameters per ELD information over HDMI
  sound: oss: sh_dac_audio.c removed duplicated #include
