Device node iterators perform an of_node_put on each iteration, so putting an of_node_put before going around to the next iteration results in a double put. The complete semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @r exists@ expression e1,e2; local idexpression n; iterator name for_each_node_by_name, for_each_node_by_type, for_each_compatible_node, for_each_matching_node, for_each_matching_node_and_match, for_each_child_of_node, for_each_available_child_of_node, for_each_node_with_property; iterator i; position p1,p2; statement S; @@ ( ( for_each_node_by_name(n,e1) S | for_each_node_by_type(n,e1) S | for_each_compatible_node(n,e1,e2) S | for_each_matching_node(n,e1) S | for_each_matching_node_and_match(n,e1,e2) S | for_each_child_of_node(e1,n) S | for_each_available_child_of_node(e1,n) S | for_each_node_with_property(n,e1) S ) & i@p1(...) { ... when != of_node_get(n) when any of_node_put@p2(n); ... when any } ) @s exists@ local idexpression r.n; statement S; position r.p1,r.p2; iterator i; @@ of_node_put@p2(n); ... when any i@p1(..., n, ...)
