[Freedreno] [PATCH] drm/msm/mdp4: Fix refcount leak in mdp4_modeset_init_intf

[Miaoqian Lin]

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.

Fixes: 86418f90a4c1 ("drm: convert drivers to use of_graph_get_remote_node")
