Currently when *obj is not a TYPE_DEVICE, qemu will abort. This patch just fixed it. When *obj is not a TYPE_DEVICE, just do not add it to hotpluggable device list. This patch also fixed the following issue: 1, boot qemu using cli: virtio-scsi-pci,id=scsi0 -enable-kvm 2, device_del scsi0 via hmp using tab key(first input device_del, then press "Tab" key). (qemu) device_del After step2, qemu will abort. (qemu) device_del hw/core/qdev.c:930:qdev_build_hotpluggable_device_list: Object 0x5555563a2460 is not an instance of type device Signed-off-by: Jun Li <junmuzi@gmail.com> --- hw/core/qdev.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-)
