Subject: [PATCH v2] mach-versatile: (platsmp-vexpress) Add missing of_node_put()
Date: Thu, 16 Jun 2022 11:59:11 +0800 [thread overview]
Message-ID: <20220616035911.3976600-1-windhl@126.com> (raw)
In vexpress_smp_dt_prepare_cpus(), of_find_matching_node() will
return a node pointer with refcount incremented. We should use
of_node_put() when it is not used anymore.
