Merge tag 'sound-5.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
 
Pull sound fixes from Takashi Iwai:
 "No big surprises here, just a few device-specific fixes.

  HD-audio received several fixes for Acer, Dell, Huawei and other
  laptops as well as the workaround for the new Intel chipset. One
  significant one-liner fix is the disablement of the node-power saving
  on Realtek codecs, which may potentially cover annoying bugs like the
  background noises or click noises on many devices.

  Other than that, a fix for FireWire bit definitions, and another fix
  for LINE6 USB audio bug that was discovered by syzkaller"
