    Subject[PATCH 5.15 181/779] ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init
    Date
    From: Miaoqian Lin <linmq006@gmail.com>

    [ Upstream commit 942228fbf5d4901112178b93d41225be7c0dd9de ]

    of_find_matching_node() returns a node pointer with refcount
    incremented, we should use of_node_put() on it when not need anymore.
    Add missing of_node_put() to avoid refcount leak.

    Fixes: 1e037794f7f0 ("ARM: OMAP3+: PRM: register interrupt information from DT")
