Agreed.

But that's not what I'm asking. See a changelog of
3eea8b5d68c801fec788b411582b803463834752 and compare it with what it
actually does.

It is buggy. If fuzz is specified but maximum is not, it overwites
maximum with zero.

Plus it introduces new failure "if (!test_bit(axis, dev->absbit))".

Plus it fails to distinguish between "value not specified in the dt"
and "zero is specified in the dt".

The 3eea8b5d68c801fec788b411582b803463834752 is just bad.
