Merge tag 'sound-4.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "There are a few fixes in ALSA core for bugs that have been spotted by
  fuzzer.  Also a temporary workaround for PowerPC (and possibly other)
  builds with incompatible ioctls was applied to compress API.

  Other than that, a few trivial fixes and quirks for FireWire BeBoB,
  USB-audio and HD-audio are found, too"

* tag 'sound-4.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - disable dynamic clock gating on Broxton before reset
  ALSA: hda - Add new GPU codec ID 0x10de0083 to snd-hda
  ALSA: dummy: Disable switching timer backend via sysfs
  ALSA: timer: fix SND_PCM_TIMER Kconfig text
  ALSA: Add missing dependency on CONFIG_SND_TIMER
  ALSA: bebob: Use a signed return type for get_formation_index
  ALSA: usb-audio: Fix TEAC UD-501/UD-503/NT-503 usb delay
  ALSA: compress: Disable GET_CODEC_CAPS ioctl for some architectures
  ALSA: seq: Degrade the error message for too many opens
  ALSA: seq: Fix incorrect sanity check at snd_seq_oss_synth_cleanup()
