From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> The only existing caller of thermal_zone_get_num_trips(), which is rcar_gen3_thermal_probe(), uses this function to put the number of trip points into a kernel log message, but this information is also available from the thermal sysfs interface. For this reason, remove the thermal_zone_get_num_trips() call from rcar_gen3_thermal_probe() and drop the former altogether. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> --- A new version, based on the discussion following the v1: https://lore.kernel.org/linux-pm/20240617183949.GO382677@xxxxxxxxxxxx/ The Renesas driver change does not depend on the previous patches in the series. --- drivers/thermal/renesas/rcar_gen3_thermal.c | 6 +----- drivers/thermal/thermal_trip.c | 6 ------ include/linux/thermal.h | 1 - 3 files changed, 1 insertion(+), 12 deletions(-) Index: linux-pm/drivers/thermal/renesas/rcar_gen3_thermal.c =================================================================== --- linux-pm.orig/drivers/thermal/renesas/rcar_gen3_thermal.c +++ linux-pm/drivers/thermal/renesas/rcar_gen3_thermal.c @@ -563,11 +563,7 @@ static int rcar_gen3_thermal_probe(struc if (ret) goto error_unregister; - ret = thermal_zone_get_num_trips(tsc->zone); - if (ret < 0) - goto error_unregister; - - dev_info(dev, "Sensor %u: Loaded %d trip points\n", i, ret); + dev_info(dev, "Sensor %u: Loaded\n", i); } if (!priv->num_tscs) { Index: linux-pm/drivers/thermal/thermal_trip.c =================================================================== --- linux-pm.orig/drivers/thermal/thermal_trip.c +++ linux-pm/drivers/thermal/thermal_trip.c @@ -55,12 +55,6 @@ int thermal_zone_for_each_trip(struct th } EXPORT_SYMBOL_GPL(thermal_zone_for_each_trip); -int thermal_zone_get_num_trips(struct thermal_zone_device *tz) -{ - return tz->num_trips; -} -EXPORT_SYMBOL_GPL(thermal_zone_get_num_trips); - /** * thermal_zone_set_trips - Computes the next trip points for the driver * @tz: a pointer to a thermal zone device structure Index: linux-pm/include/linux/thermal.h =================================================================== --- linux-pm.orig/include/linux/thermal.h +++ linux-pm/include/linux/thermal.h @@ -210,7 +210,6 @@ int for_each_thermal_trip(struct thermal int thermal_zone_for_each_trip(struct thermal_zone_device *tz, int (*cb)(struct thermal_trip *, void *), void *data); -int thermal_zone_get_num_trips(struct thermal_zone_device *tz); void thermal_zone_set_trip_temp(struct thermal_zone_device *tz, struct thermal_trip *trip, int temp);
