for_each_compatible_node 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_compatible_node(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/platforms/powernv/opal-lpc.c | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/powerpc/platforms/powernv/opal-lpc.c b/arch/powerpc/platforms/powernv/opal-lpc.c index e4169d6..d28c4a9 100644 --- a/arch/powerpc/platforms/powernv/opal-lpc.c +++ b/arch/powerpc/platforms/powernv/opal-lpc.c @@ -401,6 +401,7 @@ void opal_lpc_init(void) if (!of_get_property(np, "primary", NULL)) continue; opal_lpc_chip_id = of_get_ibm_chip_id(np); + of_node_put(np); break; } if (opal_lpc_chip_id < 0) -- 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
