[PATCH 12/15] thermal/core: Register with the trip points

From: Daniel Lezcano
Date: Tue Apr 26 2022 - 18:16:24 EST


As we added the thermal trip points structure in the thermal zone,
let's extend the thermal zone register function to have the thermal
trip structures as a parameter and store it in the 'trips' field of
the thermal zone structure.
