The coccinelle scripts are one thing. I am quite familiar with it, so I regard this as "work but doable". My main headache is that I am not sure about the best way to upstream the result. I'd like to avoid a flag-day where all drivers across all subsystems need to be converted, but I don't really see a way around it. Preparing such a branch and make sure it does not regress is quite some work on a moving target.
