[PATCH 09/13] drm/sun4i: tcon: Drop remote endpoint reference

[Jernej Skrabec]

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.

Fixes: e8d5bbf7f4c4 ("drm/sun4i: tcon: get TCON ID and matching engine with remote endpoint ID")
