This is insanity; we can never guarantee 100% of anything.

Better is better. And 99% is better than 90%

% git grep quirks | wc -l
1585

Moreover, Linux already does quirks, and when there are quirks it
means there's no 100% guarantee of the thing working as it should;
hence the need for quirks, which is never complete, never 100%.

Anyway, screw the users, right? All you care about is that the code
looks good to you.

If we care about the users, we would provide a consistent interface,
where 0 means the same thing on all the backlight drivers. If all we
can do is provide this consistency 99% of the time through quirks,
that is the way to go.
