Description

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. Patchwork: https://patchwork.freedesktop.org/patch/488473/
