/**
Assume the callers lock everything with drm_modeset_lock_all. This change had to be done after converting suspend/resume to use atomic_state so the atomic state is preserved, otherwise all transitional state is erased. Now all callers of .crtc_enable and .crtc_disable go through atomic modeset! :-D Changes since v1: - Only check for crtc_state->active in valleyview_modeset_global_pipes. - Only check for crtc_state->active in modeset_update_crtc_power_domains. Changes since v2: - Rework on top of the changed patch order.
