OK, I see. I'll try to follow design patterns for the regulator.
Thanks a lot for your comment.

Best Regards,

Yeah, regulator usage should essentially never be conditional at a
driver level unless there's actual optional supplies in the hardware.
The situation has never been any different to that.
