Wysocki Two sysfs show/store functions for attributes representing thermal instances, trip_point_show() and weight_store(), retrieve the thermal zone pointer from the instance object at hand, but they may also get it from their dev argument, which is more consistent with what the other thermal sysfs functions do, so make them do so. No intentional functional impact. Signed-off-by: Rafael J.
