Subject: [PATCH 2/5] pinctrl: sirf: add missing of_node_put
Date: Mon, 21 Dec 2015 16:39:45 +0000 [thread overview]
Message-ID: <1450715988-4770-3-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1450715988-4770-1-git-send-email-Julia.Lawall@lip6.fr>
for_each_child_of_node performs an of_node_get on each iteration, so a
return from 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,e1;
@@
for_each_child_of_node(e1,n) {
...
(
of_node_put(n);
|
e = n
|
return n;
|
+ of_node_put(n);
? return ...;
)
...
}
// </smpl>
