From: David S. Miller <davem@xxxxxxxxxxxxx>
commit 7b566f70e1bf65b189b66eb3de6f431c30f7dff2 upstream.
This reverts:
ef1b5bf506b1 ("net: phy: Fix not to call phy_resume() if PHY is not attached")
8c85f4b81296 ("net: phy: micrel: add toggling phy reset if PHY is not attached")
Andrew Lunn informs me that there are alternative efforts
underway to fix this more properly.
