    Subject[PATCH 5.10 267/390] powerpc/powernv: add missing of_node_put() in opal_export_attrs()
    Date
    From: Zheng Yongjun <zhengyongjun3@huawei.com>

    [ Upstream commit 71a92e99c47900cc164620948b3863382cec4f1a ]

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