- * usb_gadget_controller_number - support bcdDevice id convention
- * @gadget: the controller being driven
- *
- * Return a 2-digit BCD value associated with the peripheral controller,
- * suitable for use as part of a bcdDevice value, or a negative error code.
- *
- * NOTE:  this convention is purely optional, and has no meaning in terms of
- * any USB specification.  If you want to use a different convention in your
- * gadget driver firmware -- maybe a more formal revision ID -- feel free.
- *
- * Hosts see these bcdDevice numbers, and are allowed (but not encouraged!)
- * to change their behavior accordingly.  For example it might help avoiding
- * some chip bug.
