From 013a41ec541d5daa0c9f2b5126d2e820902c052d Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 19 Jul 2011 15:38:56 -0700 Subject: [PATCH] drm/i915: provide more error output when mode sets fail If a mode set fails we may get a message from drm_crtc_helper if we're lucky, but it won't tell us anything about *why* we failed to set a mode. So add a few DRM_ERRORs for the cases that shouldn't happen so we can debug things more easily.
