From 32817580e79bb129e5ea78285109c6119ff40fd0 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Fri, 10 May 2019 22:17:28 +0800 Subject: [PATCH] ath79: ag71xx: defer probe if of_phy_connect failed gmac0 may need a phy on builtin switch, which can be unavailable if gmac0 is probed before builtin switch. Return -EPROBE_DEFER in this case so that gmac0 can be probed later.
