From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> To make the fastboot checks at least somewhat sensible let's mark the expected DPLL as the active one right after we finished the state computation. Otherwise intel_pipe_config_compare() will always be comparing things against NULL/0. TODO: This is still not really right. If the previous commit had to fall back to the other PLL then the comparisong will now fail. I guess intel_pipe_config_compare() should rather be comparing port_dplls[] instead. But to do that we really should just unify every platform to use the port_dplls[] approach whether they have any need for PLL fallbacks or not.
