4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Doug Berger <opendmb@xxxxxxxxx>
[ Upstream commit 7627409cc4970e8c8b9de6945ad86a575290a94e ]
Since the internal PHY is powered up during the open and resume
functions it should be powered back down if the functions fail.
Fixes: 1c1008c793fa ("net: bcmgenet: add main driver file")
