[PATCH net v2 1/5] net: dsa: fix fixed-link-phy device leaks
From: Johan Hovold
Date: Thu Nov 24 2016 - 13:23:44 EST
Make sure to drop the reference taken by of_phy_find_device() when
registering and deregistering the fixed-link PHY-device.
Fixes: 39b0c705195e ("net: dsa: Allow configuration of CPU & DSA port
speeds/duplex")
