From 4be0731786de10d0e9ae1d159504c83c6b052647 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Tue, 21 Apr 2015 17:13:01 +0300 Subject: [PATCH] drm/i915: Add crtc states before calling compute_config() The function intel_modeset_compute_config() needs to eventually become part of atomic_check(). At that point, all the affected crtcs need to be in the atomic state with the new values. So move the logic of adding crtc states out of that function. v2: Set crtc_state->enable in all cases.
