Even if the usb gadget framework is limited to work with one driver, it could be useful to have a kernel build with more than driver. This allow to make generic kernel that work with different udc controller.
The only blocker to do that is usb_gadget_register_driver and usb_gadget_unregister_driver function are declared in each driver.
For avoiding that a redirection is done for these functions : At probe time the driver register them (usb_gadget_register and usb_gadget_unregister), and the generic usb_gadget_register_driver and usb_gadget_unregister_driver call these callback. We pass struct *usb_gadget in usb_gadget_register and usb_gadget_unregister for flexibility (we can latter do a more complex dispatcher).
