Subject: [POWERPC] cell/cbe_regs.c: Add missing of_node_put
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1fe58a875e4bb08125c657b1b91ac515d2bdbcbe;p=linux-beck.git

[POWERPC] cell/cbe_regs.c: Add missing of_node_put

There should be an of_node_put when breaking out of a loop that iterates
using for_each_node_by_type.

This was detected and fixed using the following semantic patch.
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
identifier d;
type T;
expression e;
iterator for_each_node_by_type;
@@

T *d;
...
for_each_node_by_type(d,...)
  {... when != of_node_put(d)
       when != e = d
(
   return d;
|
+  of_node_put(d);
?  return ...;
)
...}
// </smpl>
