From: Florian Fainelli <f.fainelli@xxxxxxxxx>
commit f49823939e41121fdffada4d583e3e38d28336f9 upstream.
In case a PHY device was probed thus in the PHY_READY state, but not
configured and with no network device attached yet, we should not be
trying to shut it down because it has been brought back into reset by
phy_device_reset() towards the end of phy_probe() and anyway we have not
configured the PHY yet.
Fixes: e2f016cf7751 ("net: phy: add a shutdown procedure")
