From: Ville Syrjälä <[email protected]> intel_mpllb_state_verify() blows up if you call it for a non-modeset/fastset commit on account of the relevant connector not being part of the overall atomic state. Currently the state checker only runs for modeset/fastset commits, but for testing purposes it is sometimes desirable to run it for other commits too. Check for modeset/fastset in intel_mpllb_state_verify() itself to make this safe.
