Second set of IIO fixes for the 3.16 cycle.
* A fix for a bug in setting threshold levels within the ad799x driver
which prevents correct setting of the thresholds.
* In ad7291 fix an case where a ERR_PTR value was returned directly
instead of having PTR_ERR applied. Hence it would report success
instead of failure.
* of_iio_channel_get_by_name returned a non null pointer if it fails
and the callee was expecting NULL to indicate failure. Fixed by
returning NULL in the error cases.
