Applied to the fixes-togreg branch of iio.git.

In theory every device should have a parent, but this fix is more
minimal than adding one for the dummy device (which we should still do
- even if it's a virtual device of some type that we create just for this
purpose).

That reminds me, I was in process of fixing this for perf drivers and
forgot to finish it off :)
