    Subject[PATCH 13/14] GPU-DRM-TTM: Delete unnecessary variable initialisations in ttm_dma_pool_init()
    From
    Date
    From: Markus Elfring <elfring@users.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.
