If anyone has any objections, please let me know. ------------------ From: Jernej Skrabec [ Upstream commit 3f77e4072630e2301efdbe521e7fca10311043ec ] sun4i_tcon_of_get_id_from_port() never drops the reference taken by of_graph_get_remote_endpoint(). The function is not only called during bind, but also on every mode set through sun8i_r40_tcon_tv_set_mux(), so the leak accumulates.
