That break is part of the fixup patch I sent in response. It will be
committed in due course.

Ah, cosmetics. I almost never review patches for comment/message style.
For me, code style and readability is all that matters.

Ditto (though not completely addressed by my patch).

Feel free to send a patch. My personal opinion is that the comments make
datasheet reading easier when they include the value of the symbolic
constants, but I won't force that view on you.
