The two provided max_scale_nano values must be multiplied by 100 and 10 respectively to achieve nano units. According to the comments:
Max scale for apds0306 is 16.326432 → the fractional part is 0.326432, which is 326432000 in NANO. The current value is 3264320.
Max scale for apds0306-065 is 14.09721 → the fractional part is 0.09712, which is 97120000 in NANO. The current value is 9712000.
Update max_scale_nano initialization to use the right NANO fractional parts.

This just missed last pull request for this cycle. I've locally advanced my fixes branch to include all the material that will merge in next couple of weeks, but for now can't push it out without making a mess of linux-next (it will be in wrong place in the sequence)
So applied, but you can't see it yet!
