[Intel-gfx] [PATCH 07/23] drm/i915: Use an atomic state for the load detect modeset
Ander Conselvan de Oliveira

Tue Mar 3 05:22:01 PST 2015
Create an atomic state and initialize it for the load detect pipe
modesets, so it doesn't break once the rest of the mode set code starts
using atomic states instead of the staged config.
