Details

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

drm/msm/mdp4: Fix refcount leak in mdp4_modeset_init_intf

of_graph_get_remote_node() returns remote device 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.
