Subject: [PATCH] arch: arm: mach-alpine: Add missing of_node_put() in alphine_cpu_pm.c
Date: Wed, 15 Jun 2022 21:24:24 +0800 [thread overview]
Message-ID: <20220615132424.3967142-1-windhl@126.com> (raw)
In alpine_cpu_pm_init(), of_find_compatible_node() will return a node
pointer with refcount incremented. We should use of_node_put() when it
is not used anymore.
