These *dummy* links are not place holders of real physical links. So they cannot come from ACPI but from topology.
OK, so this is something that should have been apparent from the changelog and if that's what's supposed to happen that shouldn be what the code does - it needs to be limited to these software only links.
But honestly this just doesn't seem like the ideal design - what this means is that we're going to need to have a dummy link in place for any link that is defined by the topology which means that we've got a hard coded limit in the drivers for this dynamically defined thing from the firmware. It'd be much nicer if we just created the links from scratch when we detect them in firmware rather than requiring these stubs.
