File 0030-Manage-Manage_add-Avoid-NULL-initialization-of-dev_s.patch of Package mdadm.7129

From fbd3e15c0a42b764b7a95fc3b2095c27cec4664a Mon Sep 17 00:00:00 2001
From: Jes Sorensen <Jes.Sorensen@redhat.com>
Date: Wed, 9 Mar 2016 14:51:03 -0500
Subject: [PATCH 255/359] Manage: Manage_add(): Avoid NULL initialization of
 dev_st
References: bsc#1081910

dev_st is only ever assigned if array->not_persistent == 0, so move
the second use of it into the same scope where the assignment is
made.
