Swapping the call order of intel_dp_destroy() and intel_dp_encoder_destroy() fixes the problem. This is because i2c_del_adapter unregisters the device which parent is intel_connector, and connectors are removed in intel_dp_destroy(). Thus intel_dp_encoder_destroy() must be called before intel_dp_destroy().
