OK, I didn't know this rule, which seems different from one maintainer
to another. I'll take this into account the next time.

I didn't try to apply the series with "git am" since neither "git
format-patch" nor scripts/checkpatch.pl output a warning.

This "git am" warning is about the last line of the ReST file which end
