5.15-stable review patch. If anyone has any objections, please let me know.

commit c9f1efabf8e3b3ff886a42669f7093789dbeca94 upstream.
of_find_compatible_node() requires a call to of_node_put() when the pointer to the node is not required anymore to decrement its refcount and avoid leaking memory.
Add the missing call to of_node_put() after the node has been used.
