6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
[ Upstream commit 574849054d97cee5be78d6c149d84685647fe774 ]
Because of of_graph_get_endpoint_count() doesn't report error,
just return count of endpoint, the return type should be unsigned.
Tidyup it.
