| |
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alison Schofield <amsfield22@gmail.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.
