Subject: [PATCH] scripts/checkpatch: roll diff tweaking into checkpatch itself
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rather than relying on external tweaks lets just do it inside
checkpatch's direct commitish handling which is QEMU specific code
anyway.
