[Qemu-devel] [PATCH v2 20/36] virtio-pci: drop BusState.allow_hotplug

[Igor Mammedov]

virtio-pci-bus is an internal object of composite
virtio-pci device and it doesn't participate in
-device/device_add hotplug flow, and since it's
not required by bus_add_child() that BUS must
be hotpluggable to be able to add child at runtime,
it's possible to drop not needed 'allow_hotplug'
field.
