I would actually prefer a v10 with the current follow-up patches merged
into the main driver. I'm getting kbuild errors for the Kconfig missing
select and the PHYS_PFN_OFFSET. So let's just spin a v10.

It would help if you post a follow-up patch for the checkpatch changes
(that's easy to review), then post a v10 with just that and the other
follow-on patches merged into the driver patch itself, and that's
what I'll use for the pull request.

Sorry, I should have seen those checkpatch.pl warnings myself, but I
discovered that my git hooks didn't use the --strict option with
checkpatch. I'd have sworn that I had added it in the past, but apparently
not :-(
