[Intel-gfx] [PATCH 12/35] drm/i915: Add crtc states before calling compute_config()
Ander Conselvan de Oliveira

Tue Apr 21 07:13:01 PDT 2015
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. (Ander)
