cpufreq: Remove cpufreq_driver check in cpufreq_boost_supported()
Currently there are three calling paths for cpufreq_boost_supported() in all as below, we can see the cpufreq_driver null check is needless since it is already checked before. <path1> cpufreq_enable_boost_support() |-> if (!cpufreq_driver) |-> cpufreq_boost_supported() <path2> cpufreq_register_driver() |-> if (!driver_data ... |-> cpufreq_driver = driver_data |-> cpufreq_boost_supported() |-> remove_boost_sysfs_file() |-> cpufreq_boost_supported() <path3> cpufreq_unregister_driver() |-> if (!cpufreq_driver ... |-> remove_boost_sysfs_file() |-> cpufreq_boost_supported() Signed-off-by: Yue Hu <huyue2@yulong.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
