Subject: [PATCH net 06/16] net: ethernet: bcmgenet: fix fixed-link phydev leaks
Date: Mon, 28 Nov 2016 19:24:59 +0100 [thread overview]
Message-ID: <1480357509-28074-7-git-send-email-johan@kernel.org> (raw)
In-Reply-To: <1480357509-28074-1-git-send-email-johan@kernel.org>
Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on probe errors and on driver unbind.
Note that we're still leaking any fixed-link PHY registered in the
non-OF probe path.
Fixes: 9abf0c2b717a ("net: bcmgenet: use the new fixed PHY helpers")
Signed-off-by: Johan Hovold <johan@kernel.org>
