[PATCH] drm/sun4i: Fix device node reference leak in sun4i_tcon_of_get_id_from_port

[Miaoqian Lin]

Fix a device node reference leak where the remote endpoint node obtained
by of_graph_get_remote_endpoint() was not being properly released.

Add of_node_put() calls after of_property_read_u32() to fix this.

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