[dpdk-dev] [PATCH v1] scripts: make checkpatch cleaner for renamed files

[David Hunt <david.hunt@intel.com>]

When a file is renamed, a normal diff will include all the code of
the renamed file, and checkpatch will find warnings and errors,
even though it's just a rename.

This change will result in a 'rename' line in the diff, resulting
in a much cleaner checkpatches result.
