NAME
       usb_gadget_unregister_driver - unregister a gadget driver

SYNOPSIS
       int usb_gadget_unregister_driver(struct usb_gadget_driver * driver);

ARGUMENTS
       driver
	   the driver being unregistered

CONTEXT
       can sleep

DESCRIPTION
       Call this in your gadget driver's module cleanup function, to tell the underlying usb controller that your driver is going away. If the
       controller is connected to a USB host, it will first disconnect. The driver is also requested to unbind and clean up any device state,
       before this procedure finally returns. It's expected that the unbind functions will in in exit sections, so may not be linked in some
       kernels.
