Do you really want all of the above in the change log ?

I am not in favor of changes like this. It doesn't solve the problem
with the old API, which is that it maintains sysfs nodes locally.
Besides, this patch changes the name from "applesmc" to "applesmcbacklight",
it creates a name attribute in the hwmon device directory while
keeping the actual hwmon attributes in the platform device directory,
and the driver has another name attribute in the platform device directory.

Given that, sorry, I can not accept this patch.
