Subject: [PATCH v7 29/29] thermal/drivers/intel: Use generic thermal_zone_get_trip() function
Date: Wed, 28 Sep 2022 23:00:59 +0200 [thread overview]
Message-ID: <20220928210059.891387-30-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20220928210059.891387-1-daniel.lezcano@linaro.org>
The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.
Convert ops content logic into generic trip points and register them with the
thermal zone.
