3.16.40-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@xxxxxxxxxx>
commit c7262aaace1b17a650598063e3b9ee1785fde377 upstream.
Make sure to drop the references taken by of_get_child_by_name() and
bus_find_device() before returning from cpsw_phy_sel().
Note that holding a reference to the cpsw-phy-sel device does not
prevent the devres-managed private data from going away.
Fixes: 5892cd135e16 ("drivers: net: cpsw-phy-sel: Add new driver...")
