Subject: [PATCH 0/2] staging: comedi: das16: fix some timer sync issues

"das16" uses a kernel timer but never removes it from the queue
synchronously at the moment.  Patch 1 makes sure this is done before it
is destroyed.  Patch 2 uses the comedi device's main spin-lock to ensure
some state shared with the timer routine is updated in an SMP-safe
manner.

1) staging: comedi: das16: deschedule timer routine on detach
2) staging: comedi: das16: use spin-lock when setting timer
