Each source entity maintains a pointer to the counterpart sink entity while an enabled link connects them. It should be managed by the setup_link callback in the media controller framework at runtime. However, enabled links which connect RPFs and WPFs that have an equivalent index number are created during initialization. This registers the pointer to a sink entity from the source entity when an enabled link is created.
