CVE-2022-50188

Estado: AnalizadaMedia (5.5)—

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

drm/meson: Fix refcount leak in meson_encoder_hdmi_init

of_find_device_by_node() takes reference, we should use put_device() to release it when not need anymore. Add missing put_device() in error path to avoid refcount leak.
