# \[PATCH AUTOSEL 5.4 4/9\] cpufreq: pmac32-cpufreq: Fix refcount leak bug - From: Sasha Levin \ - Date: 2022-07-06 15:36:39 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2022/07/1849065 - Thread: https://ratatoskr.run/stable/2022/07/1849061/t.md ```text From: Liang He [ 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().
