I was just troubled that the title was saying "remove debug" and
that the body was saying "remove inline". I genuinely thought
that you inadvertently squashed two different patches
together.

I just expect the body of the patch to give extended explanations
of what is in the title, not to introduce something else, and
this regardless of the number of lines being changed.

I used to include them in the past because of
get_maitainer.pl. But Oliver pointed out that it is not
necessary. Now, I just sent it to linux-can and Marc (and maybe
some driver maintainers when relevant).
