| H A D | aloop.c | 98d21df4 Fri Mar 18 01:31:53 CDT 2011 Takashi Iwai <tiwai@suse.de> ALSA: aloop - Fix possible IRQ lock inversion
loopback_pos_update() can be called in the timer callback, thus the lock
held should be irq-safe. Otherwise you'll get AB/BA deadlock together
with substream->self_group.lock.
