Subject: [PATCH] net: bcmgenet: Remove phy_stop() from bcmgenet_netif_stop()
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: 93e0401e0fc0c54b0ac05b687cd135c2ac38187c

[ Upstream commit 93e0401e0fc0c54b0ac05b687cd135c2ac38187c ]

The call to phy_stop() races with the later call to phy_disconnect(),
resulting in concurrent phy_suspend() calls being run from different
CPUs. The final call to phy_disconnect() ensures that the PHY is
stopped and suspended, too.
