Well, I would like to avoid changing the (semantics of the) CI API .
Anyway, if you make your code available we can then discuss if
your proposed changes are after all a good thing.
I'd like to hear Ralph's or Marcus's opinion, as they originally
wrote the CI code in the av7110 firmware and driver, and I think
they know a good deal more about that stuff than I do.
