Subject: [PATCH v1 6/6] thermal: core: Avoid calling .trip_crossed() for critical and hot trips
Date: Fri, 10 May 2024 16:20:25 +0200 [thread overview]
Message-ID: <3229987.5fSG56mABF@kreacher> (raw)
In-Reply-To: <13518388.uLZWGnKmhe@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Invoking the governor .trip_crossed() callback for critical and hot
trips is pointless because they are handled directly by the core,
so make thermal_governor_trip_crossed() avoid doing that.
