cpufreq: s5pv210: add missing of_node_put()
for_each_compatible_node performs an of_node_get on each iteration, so a
return from 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,e2;
statement S;
iterator i1;
iterator name for_each_compatible_node;
@@
for_each_compatible_node(n,e1,e2) {
...
(
of_node_put(n);
|
e = n
|
return n;
|
i1(...,n,...) S
|
+ of_node_put(n);
? return ...;
)
...
}
// </smpl>
Additionally, call of_node_put on the previous value of np, obtained from
of_find_compatible_node, that is no longer accessible at the point of the
for_each_compatible_node.
