Subject: [PATCH] Driver Core: do not oops when driver_unregister() is called
 for unregistered drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

We also fix a problem with cleaning up properly when initializing
drivers and devices, so checks like this will work successfully.
