Subject: [PATCH 3.16.y-ckt 46/94] ARM: orion: Fix DSA platform device after mvmdio conversion

3.16.7-ckt20 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@...il.com>

commit d836ace65ee98d7079bc3c5afdbcc0e27dca20a3 upstream.

DSA expects the host_dev pointer to be the device structure associated
with the MDIO bus controller driver. First commit breaking that was
c3a07134e6aa ("mv643xx_eth: convert to use the Marvell Orion MDIO
driver"), and then, it got completely under the radar for a while.

Reported-by: Frans van de Wiel <fvdw@...w.eu>
Fixes: c3a07134e6aa ("mv643xx_eth: convert to use the Marvell Orion MDIO driver")
