4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alison Schofield <amsfield22@gmail.com>
commit d1aaf20ee655888c227d5137b7a63551f8d15416 upstream.
The suspend/resume functions were using dev_to_iio_dev() to get the iio_dev. That only works on IIO dev's. Use dev_get_drvdata() for a platform device to get the correct iio_dev.
