ALSA: dummy - Better jiffies handling
In the system-timer mode, snd-dummy driver issues each tick to update the position. This is highly inefficient and even inaccurate if the timer can't be triggered at each tick. Now rewritten to wake up only at the period boundary. The position is calculated from the current jiffies. Signed-off-by: Takashi Iwai <tiwai@suse.de>
