There should be an of_node_put when breaking out of a loop that iterates over calls to of_find_all_nodes, as this function does an of_node_get on the value it returns. This was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; identifier d; expression e; @@ T *d; ... for (d = NULL; (d = of_find_all_nodes(d)) != NULL; ) {... when != of_node_put(d) when != e = d ( return d; | + of_node_put(d); ? return ...; ) ...} // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mackerras <paulus@samba.org> |
