 * drm_mode_connector_set_path_property - set tile property on connector

 *

 * This creates a property to expose to userspace to specify a

 * connector path. This is mainly used for DisplayPort MST where

 * connectors have a topology and we want to allow userspace to give

 * them more meaningful names.

 *

 * Returns:

 * Zero on success, errno on failure.
