From bdc22c8d52d70fc5655ab4dbf72fa79b034bb7b5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 5 Dec 2023 20:18:39 +0100 Subject: thermal: trip: Send trip change notifications on all trip updates The _store callbacks of the trip point temperature and hysteresis sysfs attributes invoke thermal_notify_tz_trip_change() to send a notification regarding the trip point change, but when trip points are updated by the platform firmware, trip point change notifications are not sent. To make the behavior after a trip point change more consistent, modify all of the 3 places where trip point temperature is updated to use a new function called thermal_zone_set_trip_temp() for this purpose and make that function call thermal_notify_tz_trip_change(). Note that trip point hysteresis can only be updated via sysfs and trip_point_hyst_store() calls thermal_notify_tz_trip_change() already, so this code path need not be changed.
