[PATCH v1 16/16] thermal: core: Relocate critical and hot trip handling
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Subject: [PATCH v1]
Modify handle_thermal_trip() to call handle_critical_trips() only after
finding that the trip temperature has been crossed on the way up and
remove the redundant temperature check from the latter.
No intentional functional impact.
