If anyone has any objections, please let me know. ------------------ From: Yangtao Li commit 7f9705beeb3759e69165e7aff588f6488ff6c1ac upstream. The of_find_compatible_node() returns a node pointer with refcount incremented, but there is the lack of use of the of_node_put() when done. Add the missing of_node_put() to release the refcount.
