--- Comment #42 from Raymond <superquad.vortex2 at gmail.com> ---
hardware pointer should be increased by one period on every period_update, the
driver report lost interrupt when the elasped time is more than 1.5 period time

no_jiffies_check:
    if (delta > runtime->period_size + runtime->period_size / 2) {
        hw_ptr_error(substream, in_interrupt,
                 "Lost interrupts?",
                 "(stream=%i, delta=%ld, new_hw_ptr=%ld, old_hw_ptr=%ld)\n",
                 substream->stream, (long)delta,
                 (long)new_hw_ptr,
                 (long)old_hw_ptr);
    }
