From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx> device_for_each_child_reverse_from() checks (!parent->p) for its parameter @parent, and that is not consistent with other APIs of its cluster as shown below: device_for_each_child_reverse_from() // check (!parent->p) device_for_each_child_reverse() // check (!parent || !parent->p) device_for_each_child() // same above device_find_child() // same above Correct the API's parameter @parent check by (!parent || !parent->p).
