So probably in RFC v2, I will have some fix. > One thing I just noticed is that the iio device number change after a suspend/wakeup cycle. For e.g., immediately after booting the in_accel_?_raw files are located in the dir /sys/bus/iio/devices/iio\:device0/ but after a suspend/wakeup the in_accel files have moved to /sys/bus/iio/devices/iio\:device3/ instead. No idea if this is relevant or not, just thought I should let you know. --  Atri Bhattacharya Fri 3 Jun 04:47:15 CEST 2016 Sent from openSUSE Tumbleweed (20160531) (x86_64) on my laptop.
