void usb_driver_release_interface (struct usb_driver * driver, struct usb_interface * iface);
This should be used by drivers to release their claimed interfaces. It is normally called in their disconnect methods, and only for drivers that bound to more than one interface in their probe.
When the USB subsystem disconnects a driver from some interface, it automatically invokes this method for that interface. That means that even drivers that used usb_driver_claim_interface usually won't need to call this.
