Takashi Iwai 8d3a8b5cb5 ALSA: mixart: Use nonatomic PCM ops 
Like the previous patch for VX boards, miXart device driver can be
also rewritten to use nonatomic PCM ops.  Simply spinlocks are
replaced with mutex, the tasklet code is merged into the threaded irq
handler.  Also, now mgr->msg_mutex is superfluous, so merged to
msg_lock.
