[PATCH v1] thermal: core: Introduce thermal_governor_trip_crossed()

[Rafael J. Wysocki]

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

Add a wrapper around the .trip_crossed() governor callback invocation
to reduce code duplications slightly and improve the code layout in
__thermal_zone_device_update().

No intentional functional impact.

Good suggestion from Daniel. That code would probably be inlined anyway
by most of compilers today, so no harm & LGTM.
