IIRC the original demand for those functions was that drivers were doing
a chain of lookups from whatever API they were working with to get back
to their driver data and that this was before there was a convenient
struct device around in all those structs.  With a struct device right
there it's less clear that's buying us much, and now you mention it I
can see the potential for surprises if people think each struct has it's
own driver data.  Don't know what other people's opinion is though?
