[alsa-devel] [PATCH][RESEND] ALSA: Add SNDRV_PCM_STATE_PAUSED case in wait_for_avail function
When the process is sleeping at the SNDRV_PCM_STATE_PAUSED state from the wait_for_avail function, the sleep process will be woken by timeout(10 seconds). Even if the sleep process wake up by timeout, by this patch, the process will continue with sleep and wait for the other state.

Hrm, still I couldn't apply it cleanly. Did you test whether git-am works with your mail?
Anyways, I applied it manually since it's just two liners.
thanks,
