Acked-By: Sebastian Reichel <s...@kernel.org> max-x/fuzz-x is a leftover from development of the generic bindings (Initially I used min and max). If 3eea8b5d68c801fec788b411582b803463834752's behaviour should become the new behaviour it should be documented, that maximum and fuzz values are dependent on each other. Instead I suggest to restore the old behaviour. -- Sebastian
