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