[PATCH] USB: make registering a usb driver automatically set the module owner
This fixes the driver that forgot to set the module owner up. Now we can remove the unneeded pointer from the usb driver structure. The idea for how to do this was from Al Viro, who did this for the PCI drivers. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
