[PATCH AUTOSEL for 4.4 009/101] net: bcmgenet: power down internal phy if open or resume fails

[alexander . levin]

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")
