module_init時にusb_registerだけ、module_exit?時にusb_deregister?だけ行う

#define module_usb_driver(__usb_driver) \
        module_driver(__usb_driver, usb_register, usb_deregister)

usb_mouse_driver?が引数の場合 

static int __init usb_mouse_driver_init(void)
{
        return usb_register(&(usb_mouse_driver) , ##__VA_ARGS__);
}
module_init(usb_mouse_driver_init);
static void __exit usb_mouse_driver_exit(void)
{
        usb_deregister(&(usb_mouse_driver) , ##__VA_ARGS__);
}
module_exit(usb_mouse_driver_exit);
