[Qemu-devel] Regression: cold plug with device_add fails assertion

[Markus Armbruster]

Test case:

$ echo -e 'device_add usb-mouse\nq' | qemu-system-x86_64 -vnc :0 -monitor stdio 
-usb

Works in v1.0, doesn't work in master's commit ab0115e1:

qemu-system-x86_64: /work/armbru/qemu/hw/qdev.c:97: qdev_create_from_info: 
Assertion `bus->allow_hotplug' failed.

Same for virtio-blk-pci, so it's not specific to USB.
