On the hardware state readout path, using crtc->config happens to work since the proper value is written to it before encoder->get_config() is called. However, in the check_crtc() path, the state will be read from the cpu_transcoder in the software tracking, instead of the one just read out from hw. Using the field in the supplied intel_crtc_state should do the right thing in both cases.
