[PATCH net v2 1/4] phy: fix device reference leaks
From: Johan Hovold <johan@kernel.org>

Make sure to drop the reference taken by bus_find_device_by_name()
before returning from phy_connect() and phy_attach().
Note that both function still take a reference to the phy device
through phy_attach_direct().
