[Sasha Levin <Alexander.Levin@xxxxxxxxxxxxx>]

From: Borislav Petkov <bp@xxxxxxx>

This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 91eefaabf102c539e6f5531e9a1e5ed46d2b41ca ]

Fix:

  drivers/net/ethernet/amd/xgbe/xgbe-main.c:835:12: warning: ‘xgbe_suspend’ defined
    but not used [-Wunused-function]
  drivers/net/ethernet/amd/xgbe/xgbe-main.c:855:12: warning: ‘xgbe_resume’ defined
    but not used [-Wunused-function]

I see it during randconfig builds here.
