Subject: [PATCH v3 07/12] thermal/core: Rename trips to ntrips
Date:   Sun,  3 Jul 2022 20:30:54 +0200
Message-Id: <20220703183059.4133659-8-daniel.lezcano@linexp.org>

In order to use thermal trips defined in the thermal structure, rename
the 'trips' field to 'ntrips' to have the 'trips' field containing the
thermal trip points.
