CVE-2022-50184

Estado: AnalizadaMedia (5.5)—

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

drm/meson: encoder_hdmi: Fix refcount leak in meson_encoder_hdmi_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.
