[PATCH] driver core: add bus_find_device & driver_find_device functions
Add bus_find_device() and driver_find_device() which allow searching for a device in the bus's resp. the driver's klist and obtain a reference on it. Signed-off-by: Cornelia Huck <cohuck@de.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
