This really is not a change worth making in existing code, IMO.

I find it a little ironic that nacking of unnecessary code churn has
spawned unnecessary code churn in the opposite direction.

I'd leave it up to maintainers of specific drivers to decide, but for
now - net-next is closed anyway, please come back with these after
merge window is over.

Thanks!
