Merge branch 'net-ocelot-switch-regressions'

Vladimir Oltean says:

====================
Regressions in Ocelot switch drivers

These are 3 patches which resolve a regression in the Seville driver,
one in the Felix driver and a generic one which affects any kernel
compiled with 2 Kconfig options enabled. All of them have in common my
lack of attention during review/testing. The patches touch the DSA, MFD
and MDIO drivers for Ocelot. I think it would be preferable if all
patches went through netdev (with Lee's Ack).
