Subject: [PATCH 1/2] drm: add helper to sort panels to the head of the connector list
Date: Sat, 27 Oct 2012 15:52:04 +0200

commit cb0953d734348e8862d6d7edc666cfb3bf6d8fae
Author: Adam Jackson <ajax@redhat.com>

    drm/i915: Initialize LVDS and eDP outputs before anything else

    This makes them sort to the front in X, which makes them likely to be
    the primary outputs if you haven't specified a preference in your DE,
    which is likely to be what you want.

Sorting the connector list after the fact is much easier than trying
to be clever with the init sequence.
