    drm/i915: prefer VBT modes for SVDO-LVDS over EDID

has a silent functional conflict with

commit 990256aec2f10800595dddf4d1c3441fcd6b2616
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>
Date:   Fri May 31 12:17:07 2013 +0000

    drm: Add probed modes in probe order

in drm-next. W simply need to add the vbt modes before edid modes, i.e. the
other way round than now.
