4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jo...@kernel.org>
commit 86e1d5adcef961eb383ce4eacbe0ef22f06e2045 upstream.
Make sure to drop the reference taken by of_find_device_by_node() when
looking up an mdio device from a phy_id property during probe.
Fixes: 549985ee9c72 ("cpsw: simplify the setup of the register
pointers")
