Subject: [PATCH] Change checkpatch.pl tab expanding to 4 characters.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The C coding style guide says that tab width is 4 characters but checkpatch.pl expands tabs to 8 characters which produces false negatives.
