From 4f3a00c7f5b2cfe4e127fd3fe49b55e1b318c01f Mon Sep 17 00:00:00 2001
From: Robert Hancock <robert.hancock@calian.com>
Date: Tue, 25 Jan 2022 10:54:08 -0600
Subject: [PATCH] net: phy: at803x: move page selection fix to config_init
The fix to select the copper page on AR8031 was being done in the probe
function rather than config_init, so it would not be redone after resume
from suspend. Move this to config_init so it is always redone when
needed.
Fixes: c329e5afb42f ("net: phy: at803x: select correct page on config init")
