It appears that proc_reg_uV might be used before initialization. It would be appropriate to initialize it at the probe function. 2. Because you are already using OPP, why don't you rely on OPP fully? (use OPP from CPUFreq drivers as well in order to get OPP events automatically.) Anyway, this is a minor item that does not need to be corrected. Cheers MyungJoo
