Subject: [PATCH] powerpc: 8xx: Fix refcount leak bug in tqm8xx_setup
Date: Sat, 18 Jun 2022 10:49:30 +0800 [thread overview]
Message-ID: <20220618024930.4056825-1-windhl@126.com> (raw)
In init_ioports(), of_find_node_by_name() will return a node pointer
with refcount incremented. We should use of_node_put() when it is not
used anymore.
