Wysocki Make the acerhdf driver use the .should_bind() thermal zone callback to provide the thermal core with the information on whether or not to bind the given cooling device to the given trip point in the given thermal zone. If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. The previously existing acerhdf_bind() function bound cooling devices to thermal trip point 0 only, so the new callback needs to return 'true' for trip point 0. However, it is straightforward to observe that trip point 0 is an active trip point and the only other trip point in the driver's thermal zone is a critical one, so it is sufficient to return 'true' from that callback if the type of the given trip point is THERMAL_TRIP_ACTIVE.
