Subject[PATCH] pinctrl: Add missing of_node_put
of_find_node_by_name does an of_node_get on its return value, 
so an of_node_put is needed on this value before the corresponding
variable goes out of scope.

The Coccinelle semantic patch used to make this change is as follows:
@@
struct device_node *n;
struct device_node *n1;
statement S;
identifier f;
expression E;
constant C;
@@

n = of_find_node_by_name(...)
...
if (!n) S
... when != of_node_put(n)
when != n1 = f(n,...)
when != E = n
when any
when strict
(
+ of_node_put(n);
return -C;
|
of_node_put(n);
|
n1 = f(n,...)
|
E = n
|
return ...;
)
