It should be noticed that the adp8870 doc was missing an entry for l1_daylight_dim, which was fixed on this patch. While the ambient light zone is device-specific, the sysfs definition is actually common. So, unify them at: Documentation/ABI/testing/sysfs-class-backlight and use as the contact point, the e-mail reported by get_maintainers.pl for the subsystem.
