From 27eb1fa9130a98edd2b321d4dbce5c8b244ee7af Mon Sep 17 00:00:00 2001 From: Christian König Date: Fri, 19 Oct 2018 13:49:05 +0200 Subject: drm/ttm: use a static ttm_mem_global instance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As the name says we only need one global instance of ttm_mem_global. Drop all the driver initialization and just use a single exported instance which is initialized during BO global initialization.
