From f9a4191cfbe86c5f96a6c6d340ab8bb65fa5c211 Mon Sep 17 00:00:00 2001 From: Lars Lindley Date: Sat, 20 Mar 2010 00:26:45 +0100 Subject: [PATCH] Staging: winbond: mto.c Coding style fixes I changed all things reported by checkpatch.pl except some long lines and the use of externs in a .c file. I also removed revision comments and "commented out" code.
