[PATCH 05/17] drm/sun4i: tcon: Release node when traversing of graph

[Jernej Skrabec]

Function sun4i_tcon_find_engine_traverse() doesn't release node if it
needs to traverse of graph deeper than 1 level.

Fix this by calling of_node_put().

Fixes: 49836b11fe71 ("drm/sun4i: tcon: Generalize engine search algorithm")
