Similar pattern as XHCI submission - it looks like you do not work on
mainline kernel, but some other, private tree with other modifications.
It seems you created this series based on that private tree.

This is not the proper process.

Please rebase all your work on recent mainline kernel (v5.18-rc1,
linux-next) and work there.

Then you can start using get_maintainers.pl...

BTW, this v2, not v1, so please version it correctly. Add also changelog
to your series in cover letter.

Best regards,
Krzysztof
