From afbc31948a007e03d6a1282677aafc2208f45819 Mon Sep 17 00:00:00 2001 From: Hannes Schmelzer Date: Fri, 29 Mar 2019 09:54:05 +0100 Subject: [PATCH] net: phy: implement fallback mechanism for negative phy adresses Negative phy-addresses can occour if the caller function was not able to determine a valid phy address (from device-tree for example). In this case we catch this here and search for ANY phy device on the given mdio- bus.
