Revision b1d4f7f4bdcf9915c41ff8cfc4425c84dabb1fde authored by Clemens Ladisch on 10 February 2011, 15:15:44 UTC, committed by Takashi Iwai on 10 February 2011, 17:53:29 UTC
If a timer interrupt was delayed too much, hrtimer_forward_now() will
forward the timer expiry more than once.  When this happens, the
additional number of elapsed ALSA timer ticks must be passed to
snd_timer_interrupt() to prevent the ALSA timer from falling behind.

This mostly fixes MIDI slowdown problems on highly-loaded systems with
badly behaved interrupt handlers.
