From: Miaoqian Lin <linmq006@xxxxxxxxx>
[ Upstream commit b23789a59fa6f00e98a319291819f91fbba0deb8 ]
of_parse_phandle() returns a node pointer with refcount incremented, we should
use of_node_put() on it when not need anymore. Add missing of_node_put() to
avoid refcount leak.
Fixes: d10715be03bd ("video: ARM CLCD: Add DT support")
