It is right that an always-on regulator should not be attempted to be disabled. But at the same time regulator framework should not return an error when such request is received. Instead it should just return success without attempting to disable the specified regulator. This is because the requesting driver will not have the idea if the regulator is always-on or not. The requesting driver will always try to enable/disable regulator as per the required flow. So it is upto regulator framework to not break such scenarios.
