Description
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.
