    Spose so. Documentation/ABI/stable/sysfs-class-backlight does have
    some stuff in it.

    Personally I tend to regard Documentation/ABI/ as fairly useless
    incomprehensible stuff, maintained to keep Greg happy ;) It'd be better
    to have a nice little well-maintained document for a subsystem such as
    this which actually explains its operation in a useful-to-humans way.
    Rather than just mechanically filling out forms.

    But a Documentation/ABI update is a heck of a lot better than nothing.
