power/reset: at91-reset: add missing of_node_put
for_each_matching_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,e1; local idexpression np; @@ for_each_matching_node(np, e1) { ... when != of_node_put(np) when != e = np ( return np; | + of_node_put(np); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Sebastian Reichel <sre@kernel.org>
