[merged mm-nonmm-stable] lib-remove-back_str-initialization.patch removed from -mm tree

[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: lib: remove back_str initialization
has been removed from the -mm tree.  Its filename was
     lib-remove-back_str-initialization.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

From: Tom Rix <trix@redhat.com>
Subject: lib: remove back_str initialization

Clang static analysis reports this false positive
glob.c:48:32: warning: Assigned value is garbage
  or undefined
  char const *back_pat = NULL, *back_str = back_str;
                                ^~~~~~~~   ~~~~~~~~

back_str is set after back_pat and it's use is protected by the !back_pat
check.  It is not necessary to initialize back_str, so remove the
initialization.
