Subject: [PATCH v1 06/10] thermal: core: Move some trip processing to thermal_trip_crossed()
Date: Wed, 16 Oct 2024 13:29:14 +0200 [thread overview]
Message-ID: <1982859.PYKUYFuaPT@rjwysocki.net> (raw)
In-Reply-To: <4958885.31r3eYUQgx@rjwysocki.net>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Notice that some processing related to trip point crossing carried out
in handle_thermal_trip() and thermal_zone_set_trip_temp() may as well
be done in thermal_trip_crossed(), which allows code duplication to be
reduced, so change the code accordingly.
No intentional functional impact.
