Subject: [PATCH v1 6/6] thermal: core: Avoid calling .trip_crossed() for critical and hot trips

From: Rafael J. Wysocki <[email protected]>

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.
