What deferred probe does is keep a list of devices that failed to bind with a deferred probe error code then every time a device does manage to bind it retries all those failed devices in case the new device provides whatever was missing from one of the others. It's a bit brute force and ignorance but it does sort things out in the end if all the drivers are actually there and just loaded in the wrong order.
