I don't have any real objection to this patch set, but as this
might be added to the Documentation tree and in .rst format,
perhaps Jonathan Corbet and/or Mauro Carvalho Chehab might have
some opinion.

Also I do not want to be a maintainer of this .rst file and
likely neither Jon nor Mauro would either.  Perhaps you?

Ideally, the patch order would be reversed so the .rst file
is added first, then checkpatch updated to use it.

And _a lot_ more types and descriptive content should be added.
