Please name this 'x-noqdev' if it is likely to be removed in the future,
to make it obvious that it is not part of the permanent API.  Also, mark
it as optional, with a sane default, so that you can test the API
without being forced to supply this temporary parameter.

Based on my comments on 3/12, if you rename that qapi to:

{ 'type': 'VMStatesQdevDevice',
  'data': { 'device': 'str' } }

then this should be

'*qdevices': [ 'VMStatesQdevDevice' ]

If noqdev is going to disappear, I wouldn't include it in the example.
Conversely, showing how to use 'devices' might be useful.
