From 92ca8241533009e4e05a9f3999a75389678af094 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Sat, 11 Jun 2016 00:13:04 +0200 Subject: [PATCH] net: au1000_eth: fix PHY detection Commit 7f854420fbfe9d49afe2ffb1df052cfe8e215541 ("phy: Add API for {un}registering an mdio device to a bus.") broke PHY detection on this driver with a copy-paste bug: The code is looking 32 times for a PHY at address 0. Fixes ethernet on AMD DB1100/DB1500/DB1550 boards which have their (autodetected) PHYs at address 31. Cc: Andrew Lunn Signed-off-by: Manuel Lauss Signed-off-by: David S.
