Subject: [PATCH] ARM: bcm: Fix refcount leak in bcm_kona_smc_init
Git-commit: cb23389a2458c2e4bfd6c86a513cbbe1c4d35e76
Patch-mainline: v6.0-rc1
References: git-fixes
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")
