Neither could I ...

I based this on device_set_of_node_from_dev(), and the it "seemed" logical to me
that a device probed from devicetree would take a refcnt on the devicetree node.

As the "logical" conflicted with my search for the automagical of_node_get(), I
need the special review query.

Cheers.
