Subject: [PATCH v2 2/2] memory: of: Fix refcount leak bug in of_lpddr3_get_ddr_timings()
Date: Tue, 19 Jul 2022 16:56:40 +0800	[thread overview]
Message-ID: <20220719085640.1210583-2-windhl@126.com> (raw)
In-Reply-To: <20220719085640.1210583-1-windhl@126.com>

We should add the of_node_put() when breaking out of
for_each_child_of_node() as it will automatically increase
and decrease the refcount.

Fixes: 976897dd96db ("memory: Extend of_memory with LPDDR3 support")
