The ucc_geth_probe function assigns to ug_info->tbi_node and
ug_info->phy_node a value returned by of_parse_phandle which returns a
new reference. Put this reference again in the error path of
ucc_geth_probe and when removing the device.

No Fixes: footer here. The problem already exists in v2.6.31-rc1 (e.g.
commit 0b9da337dca9 (net: Rework ucc_geth driver to use of_mdio
infrastructure)). Didn't continue to research a specific commit.
