Sure. The issue is that rtc_update_irq calls schedule_work with rtc->irqwork
which has not been initialized. The reason for that is that rtc_device_register
has never been called.. uh wait, that does not make sense, it is called in
cmos_do_probe. Hmm, let get find out exactly on which variable queue_work_on
bombs out on.
