Merge tag 'sound-fix-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Two peaks in diffstat are for the audio EQ init of IDT codecs and the
  EMU2004 usb mixer addition, both of which are pretty device-specific,
  so safe to apply.  The rest are a bunch of small fixes, most of them
  are regression fixes"
