ALSA: fireworks/firewire-lib: Add a quirk to reset data block counter at bus reset
Fireworks has a quirk to reset data block counter at bus reset. This commit adds a flag of CIP_SKIP_DBC_ZERO_CHECK. This flag has an effect to skip checking dbc continuity when dbc is zero. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
