Description OSIDB Bzimport 2025-06-18 12:08:47 UTC 
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.
