[PATCH] bus: arm-cci: Add missing of_node_put
From: Amitoj Kaur Chawla
Date: Thu Jan 21 2016 - 22:21:52 EST
for_each_child_of_node performs an of_node_get on each iteration, so
to break out of the loop an of_node_put is required.
Found using Coccinelle. The semantic patch used for this is as follows:
// <smpl>
@@
expression e;
local idexpression n;
@@
for_each_child_of_node(n, ...) {
... when != of_node_put(n)
when != e = n
(
return n;
+ of_node_put(n);
? return ...;
)
...
}
// </smpl>
