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

Pull sound fixes from Takashi Iwai:
 "The amount of the changes isn't as quite small as wished, nevertheless
  they are straight fixes that deserve merging to 4.14 final.

  Most of fixes are about ALSA core bugs spotted by fuzzer: a follow-up
  fix for the previous nested rwsem patch, a fix to avoid the resource
  hogs due to too many concurrent ALSA timer invocations, and a fix for
  a crash with SYSEX MIDI transfer over OSS sequencer emulation that is
  used by none but fuzzer.

  The rest are usual HD-audio and USB-audio device-specific quirks,
  which are safe to apply"
