函数名称：get_next_freq - Compute a new frequency for a given cpufreq policy

函数原型：static unsigned int get_next_freq(struct sugov_policy *sg_policy, unsigned long util, unsigned long max)

返回类型：unsigned int

参数：

类型参数名称
struct sugov_policy *sg_policy
unsigned longutil
unsigned longmax
172  policy等于policy
173  freq等于如果arch_scale_freq_invariant()则max_freq否则 in kHz, only needed if cpufreq * governors are used
176  freq等于map_util_freq(util, freq, max)
178  如果freq恒等于cached_raw_freq且非need_freq_update则返回:next_freq
181  need_freq_update = false
182  cached_raw_freq等于freq
183  返回:cpufreq_driver_resolve_freq(policy, freq)
