From 4f359b653f7f598c29a1fbcf69fa975bf510061b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C5=81ukasz=20Stelmach?= Date: Wed, 30 Sep 2020 16:25:25 +0200 Subject: net/smscx5xx: change to of_get_mac_address() eth_platform_get_mac_address() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use more generic eth_platform_get_mac_address() which can get a MAC address from other than DT platform specific sources too. Check if the obtained address is valid. Signed-off-by: Łukasz Stelmach Signed-off-by: David S.
