[PATCH] driver core: change bus_rescan_devices to return void
No one was looking at the return value of bus_rescan_devices, and it really wasn't anything that anyone in the kernel would ever care about. So change it which enabled some counting code to be removed also. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
