Subject:
 [PATCH v1 05/10] thermal: core: Pass trip descriptor to
 thermal_trip_crossed()

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

In preparation for subsequent changes, modify thermal_trip_crossed()
to take a trip descriptor pointer instead of a pointer to struct
thermal_trip and propagate this change to thermal_zone_trip_down().

No functional impact.
