NAME
       usb_composite_register - register a composite driver

SYNOPSIS
       int usb_composite_register(struct usb_composite_driver * driver);

ARGUMENTS
       driver
	   the driver to register

CONTEXT
       single threaded during gadget setup

DESCRIPTION
       This function is used to register drivers using the composite driver framework. The return value is zero, or a negative errno value. Those
       values normally come from the driver's bind method, which does all the work of setting up the driver to match the hardware.

       On successful return, the gadget is ready to respond to requests from the host, unless one of its components invokes usb_gadget_disconnect
       while it was binding. That would usually be done in order to wait for some userspace participation.
