-Subject: [PATCH 17/76] thermal: Allow sensor ops to fail with -ENOSYS
-
-The thermal core uses the existence of the .get_temp, .get_trend and
-.set_emul_temp to detect whether this operation exists and should be
-used or whether it should be emulated in software. This makes problems
-for of-thermal which has to modify the struct thermal_zone_device_ops
-during runtime whenever a sensor is registered or unregistered.
-
-Let the core test for -ENOSYS from these callbacks and treat it like
-if the callbacks were not present.
-
-This allows of-thermal to always set the sensor related callbacks and
-to make struct thermal_zone_device_ops const again.
