All available links are available the /sys/class/devlink/ directory [1]. You can check them to see if each each provider/consumer are correct. Also, for each device you can find suppliers [2] the device depends on and consumers of the device in its device directory [3]. for instance in /sys/bus/platform/devices/foo/ for the foo device.
