Subject: [PATCH 13/14] GPU-DRM-TTM: Delete unnecessary variable
 initialisations in ttm_dma_pool_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 22 Sep 2016 17:37:24 +0200

Two 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.
