Subject: b43legacy: Fix unload oops if firmware is not available
From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>
commit 452028665312672c6ba9e16a19248ee00ead9400 upstream.
The asyncronous firmware load uses a completion struct to hold firmware
processing until the user-space routines are up and running. There is.
however, a problem in that the waiter is nevered canceled during teardown.
As a result, unloading the driver when firmware is not available causes an oops.
