In fact, these are the well known and commonly accepted names for these
data values, as given in the USB specification and used in many other
places in the Linux USB stack. See for example the definition of
struct usb_ctrlrequest in include/uapi/linux/usb/ch9.h.

Changing them here would only make the code less readable.
