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. [apw@canonical.com: simplified filename logic slightly, added tests] Cc: Andy Whitcroft <apw@canonical.com> Acked-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Rabin Vincent <rabin.vincent@stericsson.com> Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
