3.5.7.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.b...@intel.com>
commit a56f992cdabc63f56b4b142885deebebf936ff76 upstream.
This is a very old bug, but there's nothing that prevents the
timer from running while the module is being removed when we
only do del_timer() instead of del_timer_sync().
The timer should normally not be running at this point, but
it's not clearly impossible (or we could just remove this.)
