Actually, that's something I didn't notice with the patch: you need a
non-NULL bus_id inorder to register the device.

Something like this for singular devices would work better:

static struct device device_i8259A = {
        name: "i8259A",
        bus_id: "0020",
};

Though, where does that bus_id come from?
