From 422d2f77803d85477df72f3153e85fd2b8c6b9e9 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Mon, 25 Jul 2016 00:42:44 +0200 Subject: [PATCH] batman-adv: Remove needless init of variables on stack Some variables are overwritten immediatelly in a functions. These don't have to be initialized to a specific value on the stack because the value will be overwritten before they will be used anywhere.
