## Overview

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

drm/mcde: Fix refcount leak in mcde_dsi_bind

Every iteration of for_each_available_child_of_node() decrements
the reference counter of the previous node. There is no decrement
when break out from the loop and results in refcount leak.
Add missing of_node_put() to fix this.
