-ENODEV so no and testing is welcomed.

However I went over both drivers to make sure that this change is safe

BTW presence of the above bugs would strongly indicate that pata_artop has
never been tested (properly) with AEC6x80[R], otherwise these bugs should
have been noticed and fixed much earlier.
