[PATCH 19/55] ALSA: es1968: Support PCM sync_stop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler.  Set card->sync_irq for enabling the missing sync_stop PCM
operation, as well as removing the superfluous synchronize_irq()
call.
