I'm okay with this change, but I think ideally it would be three
patches in a series:
patch 1) as your v1;
patch 2) sorting the headers (as here);
patch 3) getting rid of "proxy" headers, e.g. kernel.h, by replacing
them with what actually is being used.

^^^ This is for sure not used as is in the driver, so definitely has
to be replaced.

It's up to the maintainers and to you to resplit, send a v3, but
again, I'm fine with this version.

I picked up v1 for this reason.

Absolutely on these being good follow up steps.

I'd prefer the split as you have it above. As such I picked v1 up
to get patch 1 of that split up.
