[PATCH net v2 1/4] phy: fix device reference leaks

From: Johan Hovold
Date: Thu Nov 03 2016 - 13:41:48 EST


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().
