3.5.7u1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Larry Finger <[email protected]> commit f89ff6441df06abc2d95f3ef67525923032d6283 upstream. When b43 fails to find firmware when loaded, a subsequent unload will oops due to calling ieee80211_unregister_hw() when the corresponding register call was never made. Commit 2d838bb608e2d1f6cb4280e76748cb812dc822e7 fixed the same problem for b43legacy.
