Subject: [PATCH v3] powerpc: macio: Make remove callback of macio driver void returned
Commit fc7a6209d571 ("bus: Make remove callback return void") forces
bus_type::remove be void-returned, it doesn't make much sense for any
bus based driver implementing remove callbalk to return non-void to
its caller.
This change is for macio bus based drivers.
