3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Johannes Berg <[email protected]> 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.)
