From 3cb480bcb3397a1cfdc04115adcdb33393fde4f9 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 1 Jun 2015 12:49:49 +0200 Subject: [PATCH] drm/i915: Use drm_atomic_helper_update_legacy_modeset_state, v2. Now that the helper is exported there's no need to duplicate this code any more. Changes since v1: - move intel_modeset_update_staged_output_state call to the right place.
