for_each_node_by_type performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ local idexpression n; expression e; @@ for_each_node_by_type(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> --- arch/powerpc/kernel/btext.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
