net: stmmac: dwmac-oxnas: fix of-node leak
Use the syscon lookup-by-phandle helper so that the reference taken by of_parse_phandle() is released when done with the node. Fixes: 5ed7414062e7 ("net: stmmac: Add OXNAS Glue Driver") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
