[qemu-s390x] hw/s390x/ipl: Dubious use of qdev_reset_all_fn

[Philippe Mathieu-Daudé]

Hi Christian,

I'm having hard time to understand why the S390_IPL object calls
qemu_register_reset(qdev_reset_all_fn) in its realize() method, while
being QOM'ified (it has a reset method).

It doesn't seem to have a qdev children added explicitly to it.
I see it is used as a singleton, what else am I missing?

Thanks,

Phil.
