clk: imx27: add missing of_node_put
for_each_compatible_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):
// <smpl>
@@
local idexpression n;
expression e;
@@
for_each_compatible_node(n,...) {
...
(
of_node_put(n);
|
e = n
|
+ of_node_put(n);
? break;
)
...
}
... when != n
// </smpl>
