This is in of itself good, but we may need to have some deprecated
elements to continue supporting what was implicitly happening with
the missnaming so as to avoid accidentally breaking someone's device
tree.

As I mentioned in my cover letter, this driver, as far as I can tell, 
only exists in your testing branch, so I find it highly unlikely that we 
would be breaking anyone. It is not in mainline and it is not even in 
linux-next.

Oops, I not only have a memory like a goldfish, I clearly didn't read your
cover letter either.

Applied to the togreg branch of iio.git and pushed out as testing.

The driver will hit next before this does but will get into mainline
in the same ultimate pull request unless something weird happens so that's
all fine.
