[PATCH 04/13] thermal: remove useless call to thermal_zone_device_set_polling

From: Sascha Hauer
Date: Tue Apr 28 2015 - 04:26:49 EST

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.
