I am not sure I understand the question. Where are we updating
target-freq ? As far as cpuinfo_cur_freq goes, there is no need to
make any changes when that is queried but..
- cpufreq core caches the currently known freq as policy->cur and uses
  it everywhere.
- When cpuinfo_cur_freq is queried, we go and check with the hardware,
  what the frequency is.
- If a difference is found, we align policy->cur with that, given it
  is still withing policy limits. That's all.
