[PATCH 5.19 0229/1157] ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ 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")
