Greg, 3f65047c853a ("of_mdio: add helper to deregister fixed-link
PHYs") needs to be backported as well for these.

Original series can be found here:

    https://lkml.kernel.org/r/1480357509-28074-1-git-send-email-johan@kernel.org

Ah, thanks for that, I thought I dropped all of the ones that caused
build errors, but missed the above one.  I'll go take the whole series
instead.

This should now all be fixed up, thanks.

While building kernel Image for arm architecture on stable-rc 4.4 branch
the following build error found.

of_mdio: add helper to deregister fixed-link PHYs
commit 3f65047c853a2a5abcd8ac1984af3452b5df4ada upstream.

Add helper to deregister fixed-link PHYs registered using
of_phy_register_fixed_link().

Convert the two drivers that care to deregister their fixed-link PHYs to
use the new helper, but note that most drivers currently fail to do so.
