From b8991403ea0f3e5b59e08e37a7ac0af8ef4264e3 Mon Sep 17 00:00:00 2001 From: Oscar Mateo Date: Tue, 28 Mar 2017 09:53:47 -0700 Subject: drm/i915/guc: Take enable_guc_loading check out of GEM core code The should happen as soon as possible, but always within the logic that depends on it (and not interrupting the top-level driver control flow).
