This contradicts the NVM Express Base Specification 2.0b, page 292: The over temperature threshold and under temperature threshold features shall be implemented for all implemented temperature sensors (i.e., all Temperature Sensor fields that report a non-zero value). Define NVME_QUIRK_NO_SECONDARY_TEMP_THRESH that disables the thresholds for all but the composite temperature and set it for this device.
