Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC. It might happen, that command when run on an older kernel, gives you outdated entries. Therefore please be sure you base your patches on recent Linux kernel.
Apologies but, this is the output of get_maintainers.pl, is there something that I missed?
I am currently working no 6.3-rc3 as my base kernel.
