From 36ccc4f89fe595567d91e3246c5d81952ba3d8b2 Mon Sep 17 00:00:00 2001 From: Chuanxiao Dong Date: Sat, 27 May 2017 17:44:18 +0800 Subject: [PATCH] drm/i915/gvt: Return -EIO if host enable_execlists not enabled when loading GVT-g GVT-g relies on the enable_execlists parameter in i915. If this option is not enabled for GVT-g, should return -EIO to make i915 driver loading failed. v2: - Use DMR_ERROR as it is a fatal message.
