those routines have everything we need to map/unmap
USB requests and it's better to use them.

    Not '&_req->req'?

of course not. _req is the usb_request not Goku's internal
representation. I could change that to:

        usb_gadget_map_request(&dev->gadget, _req, ep->is_in);

though.

   Yes, I've corrected myself already.
