Subject: [PATCH 22/46] selinux: Delete an unnecessary variable initialisation
 in range_read()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 14 Jan 2017 20:40:12 +0100

The local variable "rt" will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation at the beginning which became
unnecessary with a previous update step.
