This is because we do not support per-sensor enable/disable. We can only
enable/disable at a sensor-group level.
This patch follows the semantic to disable a sensor group iff all the sensors
belonging to that group have been disabled. Otherwise the sensor alone is marked
to be disabled and returns -ENODATA on reading it.
And a sensor group will be enabled if any of the sensor in that group is
enabled.
I will make changes to the remaining code according to your suggestion.
Thanks and Regards,
Shilpa
