Wait for the timer to really quit, not only by ensuring it is not in the critical section.

BTW the spin_lock in here does not disable BH, so that it could deadlock.

The stop function is called from the PCM trigger callback which is irq-disabled. So, you can't use del_timer_sync() here.

The same as 3/3 I was looking at compr* :(. Ignore this one, then.

thanks,
