Yes, expected by the API from day one.

If you want an API to do something else, write a new API. Don't go shoehorning
behaviour into a generic API that is driver specific.

So please fix the DDX or I'll push the patch and you can revert it if
you don't like but at least
then I know you are being painful and I can justify carrying the patch
upstream until the
Intel DDX is no longer something we care about.

Dave.
