Subject[PATCH v1 16/16] thermal: core: Relocate critical and hot trip handling
Date
From: Rafael J. Wysocki <rafael.j.wysocki@intel.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.
