From 46a3f4a3148684f9210767784a017314876c3274 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 24 Sep 2013 12:55:40 +0100 Subject: [PATCH] drm/i915: Add some debug spam for intialising SDVO During SDVO initialisation it would be useful to a have a record of the individual devices we try to enable and later probe - in particular to be able to see which fail.
