Subject: [PATCH 3/9] md/dm-table: Delete an unnecessary variable
 initialisation in dm_table_register_integrity()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 07:25:43 +0200

The local variable "template_disk" is reassigned by a statement
at the beginning. Thus omit the explicit initialisation.
