I've got mixed feelings about this. On the one hand, removing extra
params is good. On the other hand, I'm thinking we should just pass
along all the encoder->compute_config hook parameters all the way to all
functions named _compute_config(), because we just keep removing and
adding these parameters as the driver evolves. We go in circles with
this.

BR,
Jani.
