OF: properties: add missing of_node_put
Add an of_node_put when the result of of_graph_get_remote_port_parent is not available. The semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @r exists@ local idexpression e; expression x; @@ e = of_graph_get_remote_port_parent(...); ... when != x = e when != true e == NULL when != of_node_put(e) when != of_fwnode_handle(e) ( return e; | *return ...; ) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Cc: stable@vger.kernel.org Signed-off-by: Rob Herring <robh@kernel.org>
