Dmitry Torokhov 43aadaf6ef net: phy: fixed_phy: fix use-after-free when checking link GPIO ...

[ Upstream commit d266f19f3a ]

If we fail to locate GPIO for any reason other than deferral or
not-found-GPIO, we try to print device tree node info, however if might
be freed already as we called of_node_put() on it.
