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@xxxxxxx> --- arch/powerpc/kernel/btext.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/powerpc/kernel/btext.c b/arch/powerpc/kernel/btext.c index 41c011c..8d05ef2 100644 --- a/arch/powerpc/kernel/btext.c +++ b/arch/powerpc/kernel/btext.c @@ -257,8 +257,10 @@ int __init btext_find_display(int allow_nonstdout) rc = btext_initialize(np); printk("result: %d\n", rc); } - if (rc == 0) + if (rc == 0) { + of_node_put(np); break; + } } return rc; } -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
