Subject: [PATCH 4.9 58/66] iio: health: afe4404: retrieve a valid iio_dev in suspend/resume

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alison Schofield <amsfield22@...il.com>

commit 802ecfc113df1e15af1d028427cbbe785ae9cc4a upstream.

The suspend/resume functions were using dev_to_iio_dev() to get
the iio_dev. That only works on IIO dev's.  Replace it with i2c
functions to get the correct iio_dev.
