This is where I was asking you to clarify what you were trying to say :/

There's no need to do any comparison because we only ever get one
selector value, there's nothing to compare it against.  We're setting it
to the dvs_vsel since normal practice is to keep the upper end of the
voltage range constant.  This isn't going to do much good if they but
anyone who actually has that use can worry about it - it's rare.
