Liang He 29f06f1905 video: fbdev: amba-clcd: Fix refcount leak bugs ...

[ Upstream commit 26c2b7d9fac42eb8317f3ceefa4c1a9a9170ca69 ]

In clcdfb_of_init_display(), we should call of_node_put() for the
references returned by of_graph_get_next_endpoint() and
of_graph_get_remote_port_parent() which have increased the refcount.

Besides, we should call of_node_put() both in fail path or when
the references are not used anymore.
