From 26b7974d9ad7f93891ee8c39ee63bd2515da7744 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 25 Oct 2015 14:57:07 +0100 Subject: net: mv643xx_eth: add missing of_node_put for_each_available_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): // @@ expression root,e; local idexpression child; @@ for_each_available_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | + of_node_put(child); ? return ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: David S.
