From c8d4bb54c11c66610aaf8829acff6aa0506c7c29 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 10 Apr 2012 13:55:48 +0200 Subject: [PATCH] drm/i915: don't silently ignore sdvo mode_set failures Unfortunately we can't abort a mode_set, but at least tell the user that something might have gone wrong when setting the sdvo input or output timing fails.
