   4 Subject: [PATCH 12/76] thermal: remove useless call to
   5  thermal_zone_device_set_polling
   6
   7 When the thermal zone has no get_temp callback then thermal_zone_device_register()
   8 calls thermal_zone_device_set_polling() with a polling delay of 0. This
   9 only cancels the poll_queue. Since the poll_queue hasn't been scheduled this
  10 is a no-op. Remove it.
