Yes, that is a buggy use of regulator_get_optional() so you should not
do that.  Unless the supply may be physically absent it should not be
used.  If you have ideas for how to safely improve the implementation of
the normal regulator_get() then it'd be better to do that, bearing in
mind that it's an API where getting things wrong can easily result in
physical damange to the system.
