[PATCH 5.15 159/779] ARM: bcm: Fix refcount leak in bcm_kona_smc_init

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit cb23389a2458c2e4bfd6c86a513cbbe1c4d35e76 ]

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: b8eb35fd594a ("ARM: bcm281xx: Add L2 cache enable code")
