Subject: [PATCH 04/13] thermal: remove useless call to thermal_zone_device_set_polling
Date: Tue, 28 Apr 2015 10:25:54 +0200	[thread overview]
Message-ID: <1430209563-647-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1430209563-647-1-git-send-email-s.hauer@pengutronix.de>

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.
