Macro module_usb_driver is used for drivers whose init and exit paths
only register and unregister to usb API. So remove boilerplate code to
make code simpler by using module_usb_driver.
This change was made with the help of the following Coccinelle
semantic patch:
//<smpl>
@a@
identifier f, x;
@@
-static f(...) { return usb_register(&x); }
@b depends on a@
identifier e, a.x;
@@
-static e(...) { usb_deregister(&x); }
@c depends on a && b@
identifier a.f;
declarer name module_init;
@@
-module_init(f);
@d depends on a && b && c@
identifier b.e, a.x;
declarer name module_exit;
declarer name module_usb_driver;
@@
-module_exit(e);
+module_usb_driver(x);
//</smpl>
