X-Git-Tag: v2.6.27-rc2~13
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5394ba0fd892291eb425649fdbc82b673e0b7956;p=pandora-kernel.git

drivers/video/fsl-diu-fb.c: add missing of_node_put

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
    when any
    when strict
(
+ of_node_put(n);
  return -C;
|
  of_node_put(n);
|
  n2 = f2(n,...)
|
  E2 = n
|
  return ...;
)
// </smpl>
