Merge tag 'sound-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 

Pull sound fixes from Takashi Iwai:
 "There are nothing scaring, contains only small fixes for HD-audio and
  USB-audio:
   - EPSS regression fix and GPIO fix for HD-audio IDT codecs
   - A series of USB-audio regression fixes that are found since 3.5
     kernel"

* tag 'sound-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: snd-usb: fix cross-interface streaming devices
  ALSA: snd-usb: fix calls to next_packet_size
  ALSA: snd-usb: restore delay information
  ALSA: snd-usb: use list_for_each_safe for endpoint resources
