[alsa-devel] [PATCH 0/8] ALSA: firewire: minor code refactoring and bug
Hi,
During a couple of weeks, I added code refactoring to all of drivers in ALSA firewire stack. But I can find some rooms for additional code refactoring and some bugs.
This patchset is for them.
Takashi Sakamoto (8): ALSA: firewire-tascam: unify stop and release method for duplex streams ALSA: fireface: unify stop and release method for duplex streams ALSA: firewire-motu: unify stop and release method for duplex streams ALSA: firewire-digi00x: unify stop and release method for duplex streams ALSA: dice: unify stop and release method for duplex streams ALSA: bebob: ensure to release isochronous resources in pcm.hw_params callback ALSA: fireworks: ensure to release isochronous resources in pcm.hw_params callback ALSA: oxfw: ensure to release isochronous resources in pcm.hw_params callback

From callbacks for pcm and rawmidi interfaces, the functions to stop
and release duplex streams are called at the same time. This commit merges the two functions.
