The end of this probe function is rather odd and probably needs sorting
out as I imagine that needs to happen before the device is exposed to
userspace.

Nothing to do with this patch though which is great.

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

Thanks,

Jonathan
