Subject: [PATCH v1 1/6] thermal: trip: Constify thermal zone argument of thermal_zone_trip_id()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Because thermal_zone_trip_id() does not update the thermal zone object
passed to it, its pointer argument representing the thermal zone can be
const, so adjust its definition accordingly.

No functional impact.
