If you think more than a few hwmon/chip drivers will benefit from
dynamically creating the attributes, then maybe we can create some
standard method for doing so, bmcsensors of course needs to
dynamically allocate things, so I'd be using them too.

An earlier idea was to create a standard sysfs function(s) for
dynamically creating device_attributes (and others), but now we will
have custom structures with an embedded device_attribute, it looks to
me like each attribute type would require it's own function.
