A bit excessive, yes. If it's just a discussion and the issue has
already been raised, add the people and move on. OTOH, imagine having
to mention the same things multiple times a day in reviews. It is
tiring.

That uses git history which doesn't really work well IMO being on the
receiving end of those. I would suggest something like this in your
.gitconfig:

[sendemail.linux]
        tocmd =" scripts/get_maintainer.pl --nogit --nogit-fallback --nol"
        cccmd ="scripts/get_maintainer.pl --nogit --nogit-fallback --nom"
        confirm = always

Then you do just 'git send-email --identity=linux ...'

Or use b4 as it does the above and works better for series.

Some internal review or training for new contributors is needed IMO.
Some companies are required to have an known/experienced kernel
developer signoff on patches before they are submitted. I don't think
you want to get to that point.

Ideally, we should only be providing comments that can be referenced
to documentation (if the tooling can't address it). In this case, I
don't think the DT spec would be the right place property order. It's
just a convention for the schema format. However, often the
documentation we do have already isn't followed, so I'm not too
motivated to add more.
