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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/meson: encoder_cvbs: Se corrige la fuga de recuento de referencias en meson_encoder_cvbs_init. `of_graph_get_remote_node()` devuelve el puntero de nodo del dispositivo remoto con el recuento de referencias incrementado. Deberíamos usar `of_node_put()` al finalizar. Se ha añadido la función `of_node_put()` que falta para evitar la fuga de recuento de referencias.
