From: Liang He <windhl@126.com> [ Upstream commit 1d43a5120ab49f22ba6c5901ad3994e254510303 ] In anx7625_parse_dt(), 'pdata->mipi_host_node' will be assigned a new reference with of_graph_get_remote_node() which will increase the refcount of the object, correspondingly, we should call of_node_put() for the old reference stored in the 'pdata->mipi_host_node'.
