From 651c99ff66ae4704021ee15136707c892ed243d6 Mon Sep 17 00:00:00 2001
From: Christian Heller <c.heller@plomlompom.de>
Date: Sat, 25 Jan 2014 18:28:46 +0100
Subject: [PATCH] Removed redundant calls for zeroing of memory, especially
 where replaceable with a single memset(ptr, 0, sizeof(struct ...)).
