n the Linux kernel, the following vulnerability has been resolved: irqchip/apple-aic: Fix refcount leak in aic_of_ic_init of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

Deberíamos usar of_node_put() en él cuando ya no lo necesitemos. Se agrega el error of_node_put() faltante para evitar la pérdida de recuento de referencias.
