These do nothing, don't implement them.
Will remove. Maybe some day.

It'd seem a bit neater to put the OF check into the parse function but
meh.
On second look, I'd agree. Easy enough to clean up.

Like I said when reviewing the binding this should not cause the driver
to fail to load.
Will fix.

It should do...  if not then make it so since that'd mean most drivers
are buggy.
Ahh, I see there is a check for NULL in the core. Will drop.
