Subject: soc/tegra: fuse: Add missing of_node_put()
Git-commit: 0a3c2dbec425b82d9af7aeb5dc9b18da398992a7
Patch-mainline: v6.1-rc1
References: jsc#PED-1763
In tegra_init_apbmisc(), of_find_matching_node() will return a node
pointer with refcount incremented. We should use of_node_put() in each
failure path or when it is not used anymore.
