Style changes should be reviewed and documented, like any other code
change, and added to Documentation/process/coding-style.rst or an
equivalent file.

Wow, you're opening the door really wide for all sorts of trivial
changes!  Hope you have the time and inclination to review and comment
on all of them.  I certainly don't.

There is a major difference between adding these sorts of checks to
the tools in the scripts directory or even to the zero day bots that
catch different sorts of errors, BEFORE code is upstreamed, and
patches like these, after the fact.

After the code has been upstreamed, it is a lot more difficult to
justify changes like this.  It impacts both code that is being
developed AND backporting bug fixes.
