Merge tag 'sound-4.20-rc4' of git://git./linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "The only significant change is for OSS PCM emulation to convert with
  kvcalloc() to address both performance and security issues. It's a
  pretty straightforward change, which should be safe.

  The rest are, as usual, device-specific small fixes for HD-audio"
