IMHO, Instead of calling this helper multiple times with different sort 
methods, let's consolidate here only. Example below:

bool bigjoiner_mode_found(int drm_fd, drmModeConnector *connector,
                          int max_dotclock)
{
   igt_sort_connector_modes(connector, sort_drm_modes_by_res_dsc);
   if (igt_bigjoiner_possible(&connector->modes[0], max_dotclock))
     return true;

   igt_sort_connector_modes(connector, sort_drm_modes_by_clk_dsc);
   return igt_bigjoiner_possible(&connector->modes[0], max_dotclock);
}
