Subject: [PATCH 4/4] btrfs: Delete an unnecessary variable initialisation in
 tree_mod_log_eb_copy()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 20 Aug 2017 22:02:54 +0200

The variable "tm_list" will eventually be set to an appropriate pointer
a bit later. Thus omit the explicit initialisation at the beginning.
