CONFIG_OF_MDIO is tristate and will be m if PHYLIB is m.  Use
IS_ENABLED macro to prevent build error:

 ERROR: "of_mdio_find_bus" [drivers/net/phy/mdio-mux.ko] undefined!

I wonder if this could be as banal as this?  Not even build tested...

Should be wrapped into commit 25106022 if it works, to ensure
bisectability.

I was able to reproduce the failure, and this patch both fixes it and 
seems correct, so...

Acked-by: David Daney<david.daney@cavium.com>

Sorry about this failure.

Wrapped into?

Commits made to my net-next tree are permanent and irreversible, so we
cannot go back and change a commit.  I never rebase my tree, too many
people use it directly and pull it into their tree, so I'd break their
world if I ever did that.
