In the Linux kernel, the following vulnerability has been resolved:

drm/meson: encoder_cvbs: Fix refcount leak in meson_encoder_cvbs_init

of_graph_get_remote_node() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
