From: Tomi Valkeinen <[email protected]> [ Upstream commit 3231573065ad4f4ecc5c9147b24f29f846dc0c2f ]
We need to know the link bandwidth to filter out modes we cannot support, so we need to have read the display props before doing the filtering. To ensure we have up to date display props, call tc_get_display_props() in the beginning of tc_connector_get_modes().
