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> @@ local idexpression n; expression e; identifier l; @@ for_each_matching_node(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? goto l; ) ... } ... l: ... when != n // </smpl> Besides the issue found by the semantic patch, this code also stores the device_node value in a list, which requires an of_node_get, and then cleans up the list on exit from the function, which requires an of_node_put.
