Merge tag 'sound-3.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "This update contains mostly only fixes for Realtek HD-audio codec
  driver in addition to a long-standing sysfs warning bug fix for
  USB-audio.

  One significant fix for Realtek codecs is the update of EAPD init
  codes.  This avoids invalid COEF setups for some codec models and may
  fix "lost sound" in some cases.

  The rest are a bit high volume but only new quirks and ALC668-specific
  COEF tables"
