The voltage changing code in this driver is broken and should be

there is a very good reason for this (which should be documented in

constraints, voltage setting in a driver is expected to be used in cases
where the voltage varies at runtime.
In addition client drivers should almost never be calling
regulator_can_set_voltage(), if the device needs to set a voltage it
needs to set the voltage and the regulator core will handle the case
where the regulator is fixed voltage. If the driver simply skips
setting the voltage if it doesn't have permission then it should just
not bother in the first place.
