Larry Finger b9116b9a2b rtlwifi: Fix locking problem introduces with commit 6539306b ... When I tested commit 6539306, I did not notice that loading an out-of-tree module turns off lockdep testing in kernel 3.2. For that reason, I missed the kernel WARNING shown below: The solution fixes the warning by partially reverting commit 6539306.
