Subject: [PATCH net 16/16] net: dsa: slave: fix fixed-link phydev leaks
Date: Mon, 28 Nov 2016 19:25:09 +0100 [thread overview]
Message-ID: <1480357509-28074-17-git-send-email-johan@kernel.org> (raw)
In-Reply-To: <1480357509-28074-1-git-send-email-johan-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>
Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on slave-setup errors and on slave destroy.
Fixes: 0d8bcdd383b8 ("net: dsa: allow for more complex PHY setups")
