4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Florian Fainelli <f.fainelli@xxxxxxxxx> commit e7c9a3d9e432200fd4c17855c2c23ac784d6e833 upstream. The Octeon driver calls into PHYLIB which now checks for net_device->dev.parent, so make sure we do set it before calling into any MDIO/PHYLIB related function. Fixes: ec988ad78ed6 ("phy: Don't increment MDIO bus refcount unless it's a different owner") Reported-by: Aaro Koskinen <aaro.koskinen@xxxxxx> Signed-off-by: Florian Fainelli <f.fainelli@xxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/staging/octeon/ethernet.c | 2 ++ 1 file changed, 2 insertions(+) --- a/drivers/staging/octeon/ethernet.c +++ b/drivers/staging/octeon/ethernet.c @@ -776,6 +776,7 @@ static int cvm_oct_probe(struct platform /* Initialize the device private structure. */ struct octeon_ethernet *priv = netdev_priv(dev); + SET_NETDEV_DEV(dev, &pdev->dev); dev->netdev_ops = &cvm_oct_pow_netdev_ops; priv->imode = CVMX_HELPER_INTERFACE_MODE_DISABLED; priv->port = CVMX_PIP_NUM_INPUT_PORTS; @@ -820,6 +821,7 @@ static int cvm_oct_probe(struct platform } /* Initialize the device private structure. */ + SET_NETDEV_DEV(dev, &pdev->dev); priv = netdev_priv(dev); priv->netdev = dev; priv->of_node = cvm_oct_node_for_port(pip, interface, -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
