Merge tag 'sound-5.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A couple of regression fixes and a fix for mutex deadlock at
  hog-unplug, as well as other device-specific fixes:

   - A commit to avoid the spurious unsolicited interrupt on HD-audio
     bus caused a stall at shutdown, so it's reverted now.

   - The recent support of AMD/Nvidia audio component binding caused a
     mutex deadlock; fixed by splitting to another mutex

   - The device hot-unplug and the ALSA timer close combo may lead to
     another mutex deadlock; fixed by moving put_device() calls

   - Usual device-specific small quirks for HD- and USB-audio drivers

   - An old error check fix in FireWire driver"
