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> @@ expression e; local idexpression n; @@ for_each_compatible_node(n,...) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/net/wireless/ath/ath6kl/init.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/wireless/ath/ath6kl/init.c b/drivers/net/wireless/ath/ath6kl/init.c index 6e473fa..12241b1 100644 --- a/drivers/net/wireless/ath/ath6kl/init.c +++ b/drivers/net/wireless/ath/ath6kl/init.c @@ -715,6 +715,7 @@ static bool check_device_tree(struct ath6kl *ar) board_filename, ret); continue; } + of_node_put(node); return true; } return false; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
