I considered the parameter type of cpufreq_create_debugfs_symlink() and then
I need following function declaration because this function didn't always need to
create symbolic link to policy->cpu. This function declaration is capable of creating
symbolic link as 'dest_cpu -> src_cpu'

+static int cpufreq_create_debugfs_symlink(unsigned int src_cpu,
+ unsigned int dest_cpu)

Thanks,
