From 3bf9a009fccea422bc355414a3bdf5f35fff9f36 Mon Sep 17 00:00:00 2001 From: Rabin Vincent Date: Tue, 26 Oct 2010 14:23:16 -0700 Subject: checkpatch: check for incorrect permissions Throw an error when a source file has been given execute permissions using the mode change line present in git diffs. Also alow the filename matching to use the "diff" line in addition to the "+++" line, since the mode change lines appear before any "+++" lines.
