Subject: [PATCH v2 04/10] thermal: Fix thermal_zone_of_sensor_register to match documentation

thermal_zone_of_sensor_register is documented as returning a pointer
to either a valid thermal_zone_device on success, or a corresponding
ERR_PTR() value.

In contrast, the function returns NULL when THERMAL_OF is configured
off. Fix this.
