It *is* a false positive if a single-line changelog is entirely
sufficient. (There are many patches whose changelogs can and should be
a single line, plus sign-offs.)

You could as well

if few_changelog_lines
warn "You have written a short changelog."
warn "Don't you want to write some more?"
warn "(PS: I don't care what you write in particular"
warn "as long as you just add more lines.)"

if many_changelog_lines
warn "You have written a long changelog."
warn "Can't you express yourselves more concisely?"
warn "(PS: I don't care what you'll omit in particular"
warn "as long as you get the line count down.)"

Well, I haven't closely watched akpm's complaints, but I'm sure he
doesn't complain about too few lines changelog, he complains about
insufficient information in the changelog.

Your checkpatch modification does not check for insufficient information
in the changelog. It only checks line count.
