4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Florian Fainelli <f.fainelli@xxxxxxxxx> [ Upstream commit a1a50c8e4c241a505b7270e1a3c6e50d94e794b1 ] Junote Cai reported that he was not able to get a DSA setup involving the Freescale DPAA/FMAN driver to work and narrowed it down to of_find_net_device_by_node(). This function requires the network device's device reference to be correctly set which is the case here, though we have lost any device_node association there. The problem is that dpaa_eth_add_device() allocates a "dpaa-ethernet" platform device, and later on dpaa_eth_probe() is called but SET_NETDEV_DEV() won't be propagating &pdev->dev.of_node properly. Fix this by inherenting both the parent device and the of_node when dpaa_eth_add_device() creates the platform device.
