Subject[PATCH 5/7] cpufreq: balance out cpufreq_cpu_{get,put} for scaling drivers using setpolicy
Date
From: Dirk Brandewie <dirk.brandewie@gmail.com>

There is an additional reference added to the driver in
cpufreq_add_dev() that is removed in__cpufreq_governor() if the
driver implements target(). Remove the last reference when the
driver implements setpolicy()
