The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct vio_driver::remove() return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea. Note there are two nominally different implementations for a vio bus: one in arch/sparc/kernel/vio.c and the other in arch/powerpc/platforms/pseries/vio.c. This patch only adapts the powerpc one. Before this patch for a device that was bound to a driver without a remove callback vio_cmo_bus_remove(viodev) wasn't called. As the device core still considers the device unbound after vio_bus_remove() returns calling this unconditionally is the consistent behaviour which is implemented here.
