Subject: [PATCH v3 11/12] thermal/of: Use thermal trips stored in the thermal zone
Date:   Sun,  3 Jul 2022 20:30:58 +0200

Now that we have the thermal trip stored in the thermal zone in a
generic way, we can rely on them and remove one indirection we found
in the thermal_of code and do one more step forward the removal of the
duplicated structures.
