[PATCH v3 8/8] ACPI: thermal: Drop unnecessary thermal zone callbacks

Rafael J. Wysocki
2023-07-25T12:25:33Z

Drop the .get_trip_type(), .get_trip_temp() and .get_crit_temp() thermal
zone callbacks that are not necessary any more from the ACPI thermal
driver along with the corresponding callback functions.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
---

v2 -> v3: Rebase on top of the v2 of the previous patch.

v1 -> v2: No changes.
