Hmm.  Now while the field name in comment and in the structure
do match, the comment is still wrong, since it is a linke to
a handler, not a deviceā€¦ :)

Do you mean to suggest the line should be changed to

  * @hotplug_device: link to a hotplug handler associated with bus.


If I understand it right, hotplug_handler is a link property of BusState, see qbus_initfn(). Tt actually points to a device, see qbus_set_hotplug_handler(), and the actually hotplug handler is reside in this device, see how qdev_get_hotplug_handler() is used.

So, base on the talking above, the original comment could be understood by me:)

Yours Sincerely,
