From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Ignore the vrefresh in the mode the user passed in and instead calculate the value based on the actual timings. This way we can actually trust mode->vrefresh to some degree. Or should we compare the user's idea of vrefresh with the one we get from the timings and return an error if they differ? We can't really be sure what the user is asking in that case.
