From a51645f70f6384ae3329551750f7f502cb8de5fc Mon Sep 17 00:00:00 2001 From: Petr Štetiar Date: Mon, 6 May 2019 23:27:04 +0200 Subject: net: ethernet: support of_get_mac_address new ERR_PTR error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There was NVMEM support added to of_get_mac_address, so it could now return ERR_PTR encoded error values, so we need to adjust all current users of of_get_mac_address to this new fact. While at it, remove superfluous is_valid_ether_addr as the MAC address returned from of_get_mac_address is always valid and checked by is_valid_ether_addr anyway.
