[PATCH 5.15 175/667] powerpc/xics: fix refcount leak in icp_opal_init()

[Greg Kroah-Hartman]

From: Lv Ruyi <lv.ruyi@xxxxxxxxxx>

[ Upstream commit 5dd9e27ea4a39f7edd4bf81e9e70208e7ac0b7c9 ]

The of_find_compatible_node() function returns a node pointer with
refcount incremented, use of_node_put() on it when done.
