Merge tag 'sound-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound update from Takashi Iwai:
 "This is the second updates for 3.5-rc1.  It's mainly for OMAP4 HDMI
  updates and the device tree updates for OMAP, in addition to a couple
  of PCM accuray improvement and Realtek ALC269VD codec support."
