Subject: [PATCH 4/4] GPU-DRM-TILCDC: Delete unnecessary variable
 initialisations in tilcdc_convert_slave_node()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 22 Sep 2016 10:15:36 +0200

Four local variables will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation which became unnecessary with
a previous update step.
