Subject: [PATCH AUTOSEL 5.15 09/18] cpufreq: pmac32-cpufreq: Fix refcount leak bug
Date: Wed, 6 Jul 2022 11:31:44 -0400 [thread overview]
Message-ID: <20220706153153.1598076-9-sashal@kernel.org> (raw)
In-Reply-To: <20220706153153.1598076-1-sashal@kernel.org>
From: Liang He <windhl@126•com>
[ Upstream commit ccd7567d4b6cf187fdfa55f003a9e461ee629e36 ]
In pmac_cpufreq_init_MacRISC3(), we need to add corresponding
of_node_put() for the three node pointers whose refcount have
been incremented by of_find_node_by_name().
