I suppose at a later date we could turn that into a union with a short
name like u (so comedidev->pcidev would become something like
comedidev->u.pcidev), which would allow us to stick a 'struct
usb_interface *' or some other hardware device wrapper struct pointer in
the same hole.  (Maybe 'h' for 'hardware' would be better than 'u'.)
