[Intel-gfx] [PATCH] drm/i915: Reuse probed LVDS modes

[Li Peng]

>From 8f45e42005abeb26e877fbeecaeb517e94027155 Mon Sep 17 00:00:00 2001

Subject: Reuse probed LVDS modes

This is an optimization that reuse probed LVDS modes
in fill_modes(), since LVDS modes have been setup at
drm_helper_initial_config(). This could help to reduce
driver boot time.
