Subject: [PATCH] cpufreq: pmac32-cpufreq: Fix refcount leak bug
Date: Sat, 18 Jun 2022 10:25:45 +0800 [thread overview]
Message-ID: <20220618022545.4056299-1-windhl@126.com> (raw)
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().
