Julia Lawall aed5029ead drivers/net/can/mscan/mpc5xxx_can.c: Add of_node_put to avoid memory leak ... Add a call to of_node_put in the error handling code following a call to of_find_matching_node. This patch also moves the existing call to of_node_put after the call to iounmap in the error handling code, to make it possible to jump to of_node_put without doing iounmap. These appear to be disjoint operations, so the ordering doesn't matter. This patch furthermore changes the -ENODEV result in the error handling code for of_find_matching_node to a return of 0, as found in the error handling code for of_iomap, because the return type of the function is unsigned. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E,E1,E2; statement S; @@ *x = (of_find_node_by_path |of_find_node_by_name |of_find_node_by_phandle |of_get_parent |of_get_next_parent |of_get_next_child |of_find_compatible_node |of_match_node |of_find_node_by_type |of_find_node_with_property |of_find_matching_node |of_parse_phandle )(...); ... if (x == NULL) S <... when != x = E *if (...) { ... when != of_node_put(x) when != if (...) { ... of_node_put(x); ... } ( return <+...x...+>; | * return ...; ) } ...> ( E2 = x; | of_node_put(x); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.
