[PATCH v1 3/3] thermal: netlink: Use for_each_trip() in thermal_genl_cmd_tz_get_trip()

From: Rafael J. Wysocki
Date: Mon Dec 04 2023 - 14:49:30 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Make thermal_genl_cmd_tz_get_trip() use for_each_trip() instead of an open-
coded loop over trip indices.

No intentional functional impact.
