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.
