4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fainelli <f.fainelli@xxxxxxxxx>
[ Upstream commit 2cfe8f8290bd28cf1ee67db914a6e76cf8e6437b ]
We are implementing a MDIO bus which is behind another one, so use the
nested version of the accessors to get lockdep annotations correct.
Fixes: 461cd1b03e32 ("net: dsa: bcm_sf2: Register our slave MDIO bus")
