Subject: [PATCH net 15/16] net: ethernet: ti: davinci_emac: fix fixed-link phydev and of-node leaks
Date: Mon, 28 Nov 2016 19:25:08 +0100 [thread overview]
Message-ID: <1480357509-28074-16-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.
Also remember to put the of-node reference on probe errors.
Fixes: 1bb6aa56bb38 ("net: davinci_emac: Add support for fixed-link
PHY")
Signed-off-by: Johan Hovold <johan@kernel.org>
