# usb\_gadget\_unregister\_driver(9)

unregister a gadget driver

## 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.
