6.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> [ Upstream commit e5f98896efb3b6350cb6f1c241394966dcbcf240 ] Pull a wrapper around thermal zone .change_mode() callback out of thermal_zone_device_set_mode() because it will be used elsewhere subsequently. No intentional functional impact. Signed-off-by: Rafael J.
