Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

For a future improvement, try to explain the 'why' rather than
'what' of a patch in the description.   This particular change
is so common I don't mind that much, but it is a good habit to
get into!

Thanks,

Jonathan

Ah, you do say to support device tree at the end, but more
detail on that would have been good!
