[PATCH 3.16 246/306] of_mdio: fix node leak in of_phy_register_fixed_link error path

[Ben Hutchings]

3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@xxxxxxxxxx>

commit 48c1699d5335bc045b50989a06b1c526b17a25ff upstream.

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")
