----------------------------------------------------------------
sound fixes for 4.20-rc1
A few device-specific fixes: a fix for SPDIF on old Creative PCI
board, and two additional fixes for the recent changes in FireWire
audio stack.
----------------------------------------------------------------
Alex Stanoev (1):
ALSA: ca0106: Disable IZD on SB0570 DAC to fix audio pops
Takashi Sakamoto (2):
ALSA: dice: fix to wait for releases of all ALSA character devices
ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size
