Takashi Sakamoto a8c0d13267 ALSA: firewire-tascam: notify events of change of state for userspace applications
In former commits, ALSA firewire-tascam driver queues events to notify
change of state of control surface to userspace via ALSA hwdep
interface.

This commit implements actual notification of the events. The events are
not governed by real time, thus no need to care underrun.
