Ok. As far as I can tell, my two patches (mfd and pci) touching
four of those files are sufficient to address all the warnings
I see on x86, arm64 and arm. I came to the same conclusion about
being able to do more as cleanups but not needing them before the
merge window.
I also checked the power and mips specific files in your list
and they should be warning-free as far as I can tell.
