-Subject: iio: hid-sensor-trigger: Fix the race with user space powering up
- sensors
-
-It has been reported for a while that with iio-sensor-proxy service the
-rotation only works after one suspend/resume cycle. This required a wait
-in the systemd unit file to avoid race. I found a Yoga 900 where I could
-reproduce this.
-
-The problem scenerio is:
-- During sensor driver init, enable run time PM and also set a
-  auto-suspend for 3 seconds.
-	This result in one runtime resume. But there is a check to avoid
-a powerup in this sequence, but rpm is active
-- User space iio-sensor-proxy tries to power up the sensor. Since rpm is
-  active it will simply return. But sensors were not actually
-powered up in the prior sequence, so actaully the sensors will not work
-- After 3 seconds the auto suspend kicks
-
-If we add a wait in systemd service file to fire iio-sensor-proxy after
-3 seconds, then now everything will work as the runtime resume will
-actually powerup the sensor as this is a user request.
-
-To avoid this:
-- Remove the check to match user requested state, this will cause a
-  brief powerup, but if the iio-sensor-proxy starts immediately it will
-still work as the sensors are ON.
-- Also move the autosuspend delay to place when user requested turn off
-  of sensors, like after user finished raw read or buffer disable
