Merge tag 'sound-4.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Unfortunately we still have received a significant amount of changes
  at the late stage, but at least all are small and clear fixes.

  There are two fixes for ALSA core stuff, yet another timer race fix
  and sequencer lockdep annotation fix. Both are spotted by syzkaller,
  and not too serious but better to paper over quickly.

  All other commits are about ASoC drivers, most notably, a revert of
  RT5514 hotword control that was included in 4.14-rc (due to a kind of
  abuse of kctl TLV ABI), together with topology API fixes and other
  device-specific small fixes that should go for stable, too"
