Subject: [PATCH v3 2/4] thermal/core: Avoid calling ->get_trip_temp() unnecessarily
Date: Fri, 15 Jul 2022 23:09:09 +0200	[thread overview]
Message-ID: <20220715210911.714479-2-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20220715210911.714479-1-daniel.lezcano@linaro.org>

As the trip temperature is already available when calling the function
handle_critical_trips(), pass it as a parameter instead of having this
function calling the ops again to retrieve the same data.
