[PATCH net 1/3] of_mdio: fix node leak in of_phy_register_fixed_link error path

From: Johan Hovold
Date: Wed Nov 16 2016 - 09:21:53 EST


Make sure to drop the of_node reference also on failure to parse the
speed property in of_phy_register_fixed_link().

Fixes: 3be2a49e5c08 ("of: provide a binding for fixed link PHYs")
