From 8c387ebbaff8652943a1cbcab496aecadc6a8875 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 25 Oct 2015 14:57:00 +0100 Subject: [PATCH] net: thunderx: add missing of_node_put for_each_child_of_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): // @@ local idexpression r.n; expression r,e; @@ for_each_child_of_node(r,n) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // Signed-off-by: Julia Lawall Signed-off-by: David S.
