Once EDID is parsed, the monitor HDMI support information is available through drm_display_info.is_hdmi. Retriving the same information is less efficient. Change to drm_display_info.is_hdmi
This is a TODO task in Documentation/gpu/todo.rst
Also, correct an inacurracy or bug in radeon_connector_get_edid()/radeon_connector_free_edid(). Two variables have EDID data: - struct radeon_connector.edid - struct drm_connector.edid_blob_ptr The second is updated by calling drm_connector_update_edid_property() or drm_get_edid() - which internally calls drm_connector_update_edid_property(). drm_display_info.is_hdmi is updated when this function is called. radeon_connector_get_edid() calls drm_get_edid() to update drm_connector.edid_blob_ptr/drm_display_info only in some cases. Change it to be always up to date, so drm_display_info is always correct. As counterpart, reset these values in radeon_connector_free_edid().
This second change is necessary for the previous one to work properly.
