Subject: [PATCH v2 5/6] thermal: gov_step_wise: Fold update_passive_instance() into its caller

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

Fold update_passive_instance() into thermal_zone_trip_update() that is
its only caller so as to make the code in question easeir to follow.

No intentional functional impact.
