Julia Lawall 4c6d8fc20b drm: rcar-du: add missing of_node_put
Add an of_node_put when the result of of_graph_get_remote_port_parent is
not available.

Add a second of_node_put if no encoder is selected (encoder remains NULL).

The semantic match that finds the first problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>
@r exists@
local idexpression e;
expression x;
@@
e = of_graph_get_remote_port_parent(...);
... when != x = e
    when != true e == NULL
    when != of_node_put(e)
    when != of_fwnode_handle(e)
(
return e;
|
*return ...;
)
// </smpl>
