[PATCH net 04/16] net: ethernet: aurora: nb8800: fix fixed-link phydev leaks
From: Johan Hovold <johan@kernel.org>
Date: 2016-11-28 18:27:38
Also in:
linux-mediatek, linux-omap, linux-renesas-soc, linuxppc-dev, lkml, netdev
Subsystem:
networking drivers, the rest · Maintainers:
Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on probe errors and on driver unbind.
Fixes: c7dfe3abf40e ("net: ethernet: nb8800: support fixed-link DT
node")
