You have to use the script when determining who to send the patch to,
you can't do it after the fact like this as it will not work at all.

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kernel, gives you outdated entries.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.

It's the second time I am writing it. I don't understand why you keep
ignoring it.

Your commit msg does not explain why do we need it.

For some USB wifi devices, if enable this feature it will reduce the
performance. Therefore, add an option for disabling HS park mode by device-tree.
