of_find_node_by_path() returns a device_node with refcount incremented.
The reference to the "/ocp" node is acquired for a WARN_ONCE check but
is never released with of_node_put(), causing a reference count leak.

Add of_node_put(np) after the WARN_ONCE check to properly release the
"/ocp" node reference.
