[Qemu-devel] [PATCH 2/5] usb: tag standalone uhci as hotpluggable

[Gerd Hoffmann <kraxel@redhat.com>]

uhci hostadapters in companion setups can't be hotplugged.  So leave
hotplug disabled for all ich9 variants (which are already tagged with
unplug = true in the info struct).  For the other variants we'll enable
hotplug and remove the companion setup properties.
