regulator_get_voltage() might be a bit expensive, many regulators will query the hardware every time. Since it's just for diagnostic purposes it'd be better to not bother and let people read the historical information from the logs.Ok, makes sense to me.
In the reply to one of Richard's comment, the volt_old will be used not only for diagnostic purpose but also for reverting voltage back when clk_set_rate fails. -- Regards, Shawn
