Commit log doesn't really match the values being subtracted

polling-delay:
   $ref: /schemas/types.yaml#/definitions/uint32
   description:
     The maximum number of milliseconds to wait between polls when
     checking this thermal zone. Setting this to 0 disables the polling
     timers setup by the thermal framework and assumes that the thermal
     sensors in this zone support interrupts.
