Subject: drivers/serial/uartlite.c: Add missing of_node_put
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=76832d8416430d6dd0575579ca1e00d1a790f4cb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drivers/serial/uartlite.c: Add missing of_node_put

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

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

identifier d;
type T;
expression e;
iterator for_each_compatible_node;

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