Subject: [PATCH] arm: mm: Add missing of_node_put()
Date: Wed, 15 Jun 2022 16:08:46 +0800 [thread overview]
Message-ID: <20220615080846.3960101-1-windhl@126.com> (raw)
In feroceon_of_init, we use of_find_matching_node() to get a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.
