From 7822492fd21a44eeb3568082b0ab915df7388061 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 21 Jun 2016 12:04:21 +0100 Subject: [PATCH] drm/i915/gvt: Mark i915.enable_gvt as false if loading fails If we update the value of i915.enable_gvt should we fail to load GVT, userspace can easily detect when it fails to load as requested.
