4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Matt Ranostay <mranostay@xxxxxxxxx> commit 5138806f16c74c7cb8ac3e408a859c79eb7c9567 upstream. IIO_CHAN_INFO_RAW was returning processed data which was incorrect. This also adds the IIO_CHAN_INFO_SCALE value to convert to a processed value.
