Currently, all fan control operations return ENXIO if unsupported operations are requested, but return EINVAL if invalid fan modes are requested on a given ThinkPad. This is not strictly correct for sysfs, so map ENXIO to EINVAL in the sysfs attribute store handlers, as we do benefit from the ENXIO in other parts of the driver code.
