drm/i915: Update connector_mask during readout, v2. The connector_mask may be used any time during the non-atomic .crtc_disable which is called before the full atomic state is set up and needs to be accurate for that reason. Changes since v1: - Update connector_mask in readout_hw_state and add a comment. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> ---
