+The variables are local to the source and do not

+Subject: [PATCH] cpufreq: qcom: Re-organise kryo cpufreq to use it for other
+ nvmem based qcom socs
+
+The kryo cpufreq driver reads the nvmem cell and uses that data to
+populate the opps. There are other qcom cpufreq socs like krait which
+does similar thing. Except for the interpretation of the read data,
+rest of the driver is same for both the cases. So pull the common things
+out for reuse.
