Subject: drivers/video/fsl-diu-fb.c: add missing of_node_put
From: Julia Lawall <julia@xxxxxxx>
of_node_put is needed before discarding a value received from
of_find_node_by_type, eg in error handling code.
The semantic patch that makes the change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
struct device_node *n;
struct device_node *n1;
struct device_node *n2;
statement S;
identifier f1,f2;
expression E1,E2;
constant C;

n = of_find_node_by_type(...)
...
if (!n) S
... when != of_node_put(n)
when != n1 = f1(n,...)
when != E1 = n

(
+ of_node_put(n);
return -C;

n2 = f2(n,...)

E2 = n

return ...;
)
