Merge tag 'sound-4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai: "Just a few small fixes: - a fix for the recursive work cancellation in a specific HD-audio operation mode - a fix for potentially uninitialized memory access via rawmidi - the register bit access fixes for ASoC HD-audio" * tag 'sound-4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda: Fix several mismatch for register mask and value ALSA: rawmidi: Initialize allocated buffers ALSA: hda - Fix cancel_work_sync() stall from jackpoll work
