[PATCH 5.10 081/112] cpufreq: pmac32-cpufreq: Fix refcount leak bug

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Liang He <windhl@xxxxxxx>

[ 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().
