Trivially fix those broken references, by copying the structs fron the header, just like other API documentation at the DVB side. This doesn't have the level of quality used at the V4L2 side of the API, but, as this documents a deprecated API, used only by av7110 driver, it doesn't make much sense to invest time making it better.
