backlight: 88pm860x_bl: Add missing of_node_put
Author: Julia Lawall <Julia.Lawall@lip6.fr>
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.
The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):
//
@@
expression root,e;
local idexpression child;
iterator name for_each_child_of_node;
@@
for_each_child_of_node(root, child) {
... when != of_node_put(child)
when != e = child
+ of_node_put(child);
? break;
...
}
... when != child
