[Qemu-devel] [PATCH v2] hw/core/register: Mark the device with cannot_instantiate_with_device_add_yet

[Thomas Huth <thuth@redhat.com>]

The "qemu,register" device needs to be wired up in source code, there
is no way the user can add this device with the "-device" parameter or
the "device_add" monitor command yet.
