ALSA: timer: Check ack_list emptiness instead of bit flag
For checking the pending timer instance that is still left on the timer object that is being closed, we set/clear a bit flag SNDRV_TIMER_IFLG_CALLBACK around the call of callbacks. This can be simplified by replace with the list_empty() call for ti->ack_list. This covers the existence more comprehensively and safely. A gratis bonus is that we can get rid of SNDRV_TIMER_IFLG_CALLBACK bit flag definition as well. Signed-off-by: Takashi Iwai <tiwai@suse.de>
