Subject: [PATCH 5.17 216/772] powerpc/xics: fix refcount leak in icp_opal_init()
From: Lv Ruyi <lv.ruyi@....com.cn>
[ Upstream commit 5dd9e27ea4a39f7edd4bf81e9e70208e7ac0b7c9 ]
The of_find_compatible_node() function returns a node pointer with
refcount incremented, use of_node_put() on it when done.
