Subject: [PATCH] ARM: actions: add missing of_node_put calls
Date:   Sun, 18 Dec 2022 14:00:21 +0100
Message-Id: <20221218130022.393749-1-martin@kaiser.cx>
MIME-Version: 1.0

Precedence: bulk

A node that is returned by of_find_compatible_node has its refcount
incremented. We have to call of_node_put when the node is no longer
needed.

Add the missing of_node_put calls in function s500_smp_prepare_cpus.
