I'd normally apply this as a fix, but to keep things simple with
the move out of staging I've just applied it to the togreg branch
of iio.git - initially pushed out as testing for the autobuilders
to play with it.

It's been there a long time an no one has noticed, so I'm guessing
any hardware platforms with this on aren't going in for power management!
