Subject: driver core: refcounting fix
From: Mike Galbraith <efault@xxxxxx>
Fix a reference counting bug exposed by commit
725522b5453dd680412f2b6463a988e4fd148757. If driver.mod_name exists, we
take a reference in module_add_driver(), and never release it. Undo that
reference in module_remove_driver().
