[PATCH] ASoC: rsnd: add missing of_node_put
From: Julia Lawall
Date: Sat Jul 15 2017 - 03:44:35 EST
for_each_child_of_node performs an of_node_get on each iteration, so a
jump out of the loop requires an of_node_put.
The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):
// <smpl>
@@
local idexpression n;
expression e,e1;
identifier l;
@@
for_each_child_of_node(e1,n) {
...
(
of_node_put(n);
|
e = n
|
+ of_node_put(n);
? goto l;
)
...
}
...
l: ... when != n
// </smpl>
