Subject[PATCH v1 04/16] thermal: gov_bang_bang: Fold thermal_zone_trip_update() into its caller
Date
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Fold thermal_zone_trip_update() into bang_bang_control() which is the
only caller of it to reduce code size and make it easier to follow.

No functional impact.
