From db4bad07371b53dbce34e8ae54d4aa93096841d6 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Fri, 31 May 2019 19:14:44 +0200 Subject: [PATCH] net: ethernet: improve eth_platform_get_mac_address pci_device_to_OF_node(to_pci_dev(dev)) is the same as dev->of_node, so we can simplify the code. In addition add an empty line before the return statement. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
