Julia Lawall e8f7f43a4a drivers/net/fs_enet/fs_enet-main.c: Add of_node_put to avoid memory leak
In this case, a device_node structure is stored in another structure that
is then freed without first decrementing the reference count of the
device_node structure.

The semantic match that finds this problem is as follows:
