2011-01-26ALSA: AACI: make fifo variables more explanitoryRussell King1-2/+2
Improve commenting and change fifo variable names to reflect their meanings. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-01-26ALSA: AACI: use snd_pcm_lib_period_bytes()Russell King1-1/+2
Use the helper rather than open-coding this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-01-25ALSA: AACI: fix multiple IRQ claimingRussell King1-0/+2
Claiming the IRQ each time a playback or capture interface is opened is wasteful; the second copy of the registered handler is identical to the first and just wastes resources. Track the number of opens and only register the handler when necessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-12-18ALSA: AACI: switch to per-pcm lockingRussell King1-1/+1
We can use finer-grained locking, which makes things easier when we gain DMA support. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
