---------------------------------------------
modprobe/684 is trying to acquire lock:
 (&hdl->lock){+.+...}, at: [<ffffffffa02919ba>] find_ref_lock+0x24/0x46 [videodev]
but task is already holding lock:
 (&hdl->lock){+.+...}, at: [<ffffffffa029380f>] v4l2_ctrl_add_handler+0x49/0x97 [videodev]
other info that might help us debug this:
 Possible unsafe locking scenario:
       CPU0
       ----
  lock(&hdl->lock);
  lock(&hdl->lock);
 *** DEADLOCK ***
 May be due to missing lock nesting notation
3 locks held by modprobe/684:
