[PATCH 5.4 070/411] ARM: versatile: Add missing of_node_put in dcscb_init

[Greg Kroah-Hartman]

From: Peng Wu <wupeng58@xxxxxxxxxx>

[ Upstream commit 23b44f9c649bbef10b45fa33080cd8b4166800ae ]

The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak.
