When a device enters an idle state (for example ASUS RC71L with s2idle) and an iio driver has a trigger attached such as iio-trig-hrtimer, after resuming the device the trigger is not triggering data acquisition. This patch series solves the problem reliably and is well tested after many cycles and many reboots.
