[PATCH 2/4] thermal: remove unnecessary call to thermal_zone_device_set_polling

From: Sascha Hauer
Date: Mon Jul 06 2015 - 03:46:52 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.
