mISDN: fix the races with timers going off just as they are deleted timer callback in timerdev.c both accesses struct mISDNtimer it's called for *and* moves it to dev->expired. We need del_timer_sync(), or we risk kfree() freeing it right under dev_expire_timer() *and* dev->expired getting corrupted. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
