Agree with Jani. It is important to check that the verbose option of
the checkpatch still works. The script actually parses the
documentation and then shows the relevant parts as verbose output to
the user. It currently relies on the specific format, but it is not
difficult to change that to use a different pattern, see sub load_docs
in checkpatch.pl.

So, please make sure the current --verbose option in checkpatch.pl
does not break.

Thanks,

Lukas
