Just a friendly note - other drivers transitioning to atomics have
done so in a more gradual manner. I believe the idea/intent was to
ensure commits are simple and straightforward enough to minimise the
cases of regressions/bugs.

Either way the decision is between you and the driver maintainer.
Speaking of which there isn't one listed in MAINTAINERS. Is that
intentional ?

Cheers,
Emil
