From 03377e381bf48d7aaa797577789551b04bce7006 Mon Sep 17 00:00:00 2001 From: Iyappan Subramanian Date: Fri, 12 Aug 2016 22:05:47 -0700 Subject: [PATCH] drivers: net: xgene: Fix backward compatibility This patch fixes the backward compatibility on handling phy_connect(), by iterating over the phy-handle, when new DT is used with older kernel.
