^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) The driver checks sensor control registers and does not export the sensors
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) that are not enabled. Anyway, a sensor that is enabled may actually be not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) connected and thus provide zero readings.
