I think this is too specific for general checkpatch. I once proposed on
the KVM mailing list that checkpatch should gain support for plugins,
allowing specific directories to provide a .checkpatch script, or
whatever, where it puts its own checks. I never followed-up by actually
proposing that to checkpatch maintainers though.

In the absence of checkpatch plugins, I think subsystem-specific
patch management tools, like patchwork, are the next best place
to put specific checks. But, I agree it's a bit late. It'd be better
if the developers could run the checks themselves before posting.
