Merge tag 'sound-4.20-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 

Pull sound fixes from Takashi Iwai:
 "Still more incoming fixes than wished at this stage, but all look like
  small and reasonable fixes.

  In addition to the usual HD-audio and USB-audio quirks for various
  devices, two notable changes are included:

   - a fix for USB-audio UAF at probing a malformed descriptor

   - workarounds for PCM rwsem mutex starvation"
