Hi,

I think that it is exactly what holders/slaves do - displaying device
hierarchy. So application can check which underlying device are related
and ask them for more info if needed (=> with system specific call,
it can be simple sysfs attribute, ioctl, whatever).

So the only request here is to keep these symlinks correct, nothing more.
Or am I missing anything?
