[Qemu-devel] [PATCH 2/3] prep_pci: Convert to QOM realizefn

[Andreas Färber]

SysBusDeviceClass' initfn merely calls SysBusDeviceClass::init, so we
can already hook up our own realizefn overwriting this behavior.

A symmetric unrealizefn is not necessary, knowing that the child's
unrealizefn is still no-op, too. Avoids ripping it out again when
recursive realization at DeviceState-level is implemented.
