We've overlooked adding DSI panels to the front of the connector
list. This seems to be the right thing to do, and I suspect this might
fix some issues, although I currently have no evidence to support this.

Out of curiosity, why driver (i915) do not create connectors
just in proper order instead of sorting them later.

commit 270b30420c5e0d5f779aa76882367f9265c5aa7d
Author: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: move panel connectors to the front
This essentially reverts
commit cb0953d734348e8862d6d7edc666cfb3bf6d8fae
Author: Adam Jackson <ajax@redhat.com>
Date: Fri Jul 16 14:46:29 2010 -0400
drm/i915: Initialize LVDS and eDP outputs before anything else
simply because it doesn't scale: It misses SDVO and DVO panels,
and now with DDI encoders on haswell this is becoming unmanageable.
Instead we simply sort the connector list after everything is
set up.
