For multi cluster SoC, the cpufreq->target_index() is re-enter function 
for each policy to change CPU frequency. In the cirtical session must 
use glocal mutex lock to avoid get wrong OPP.

Mark Tseng (2):
  PM / devfreq: mediatek: protect oop in critical session
  cpufreq: mediatek: Fixed cpufreq has 2 policy will cause concurrency
