It might happen, that command when run on an older kernel, gives you outdated entries.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/get_maintainer.pl provide you proper list of people, so fix your workflow. Tools might also fail if you work on some ancient tree (don't, instead use mainline) or work on fork of kernel (don't, instead use mainline). Just use b4 and everything should be fine, although remember about `b4 prep --auto-to-cc` if you added new patches to the patchset. This is odd considering previously you sent it to maintainers. Best regards, Krzysztof

The description makes it sound like there could be other supplies,
but there aren't. It is the "everything" supply, so we can just
call it the power supply.

It looks like MAX22007 is not in alphabetical order. Let's fix it
first so we can put this new one in the right place.
