While this fixes obvious error I doubt that apply_uV should be set based
on min max equality. It have required fix to fixed regulator[1]
as well for max8997[2]. It'll probably require fixes in other places too.

Wouldn't it be better to explicitly use property like
"regulator-voltage-apply" in DT to set apply_uV?

if (min_uV && max_uV && constraints->min_uV == constraints->max_uV
&& of_find_property "regulator-voltage-apply")
constraints->apply_uV = true;

This would be consistent with handling of this flag from platform data.
