Browse source 
- Add a flag to mark OPPs that are not referenced by he OPP
    core any more to prevent OPPs from being freed prematurely
    by mistake (Beata Michalska).
 
  - Add ARM Vexpress platforms to the cpufreq-dt-platdev blacklist
    since the actual scaling of them is handled elsewhere (Sudeep
    Holla).
 
  - Fix a function return value check and a possible use-after-free
    in the qcom-hw cpufreq driver (Shawn Guo, Wei Yongjun).
