Subject: [PATCH 09/13] thermal: of: always set sensor related callbacks
Date: Thu, 26 Mar 2015 16:53:56 +0100	[thread overview]
Message-ID: <1427385240-6086-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1427385240-6086-1-git-send-email-s.hauer@pengutronix.de>

Now that the thermal core treats -ENOSYS like the callbacks were
not present at all we no longer have to overwrite the ops during
runtime but instead can always set them and return -ENOSYS if no
sensor is registered.
