Date: Tue, 7 Feb 2017 13:59:33 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Alison Schofield <amsfield22@...il.com>, "Andrew F. Davis" <afd@...com>, Jonathan Cameron <jic23@...nel.org> Subject: [PATCH 4.9 59/66] iio: health: afe4403: 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 a5badd1e97e6caeca78ad74191f12fc923c403a8 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 spi functions to get the correct iio_dev.
