[PATCH 5.4 173/255] powerpc/powernv: add missing of_node_put() in opal_export_attrs()

[Greg Kroah-Hartman]

From: Zheng Yongjun <zhengyongjun3@xxxxxxxxxx>

[ Upstream commit 71a92e99c47900cc164620948b3863382cec4f1a ]

After using 'np' returned by of_find_node_by_path(), of_node_put()
need be called to decrease the refcount.
