Do you have workaround for that? In my case suspending and resuming 
doesn't help. Sensor reporting is backing to work in unpredictable way. 
What I've tested:

- kernel v4.13-rc1 with your patch applied
- watch -n1 cat /sys/bus/iio/devices/iio\:device*/*_raw <- value not 
changing
- suspend
- resume
- watch -n1 cat /sys/bus/iio/devices/iio\:device*/*_raw <- still not 
changing

If you have some workaround scenario please add it to bug reported be 
me: https://bugzilla.kernel.org/show_bug.cgi?id=195681

Cheers,
