Subject: you just ignored my comment...

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). 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happen, that command when run on an older kernel, gives you outdated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.

Tools like b4 or scripts_getmaintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, use mainline), work on fork of kernel (don't, use
mainline) or you ignore some maintainers (really don't). Just use b4 and
all the problems go away.

This does not look like proper encoding.

It does not make sense. You said above adc6120 is not compatible with
pcm6240.

No need for items.

Where is adc6120 and others?

Missing blank line.
