[Qemu-devel] [PATCH] hw/misc/auxbus.c: Mark the aux-to-i2c-bridge device as non-hotpluggable

[Thomas Huth <thuth@redhat.com>]

QEMU currently aborts if the user tries to do something like this:

$ aarch64-softmmu/qemu-system-aarch64 -S -M integratorcp -nographic
QEMU 2.9.93 monitor - type 'help' for more information
(qemu) device_add aux-to-i2c-bridge,id=x
(qemu) device_del x
**
ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl)
Aborted (core dumped)

Looks like the device is not hot-pluggable, so let's mark it
accordingly.
