When the windows8 related backlight problems became evident, 2 approaches
were follow in paralellel, one was to stop claiming to be windows 8 / 2012,
the other was to tell acpi_video to stop registering a backlight driver.

I've read all the threads and it seems that which approach ended up being
applied to which model laptop was never really a concious decision (AFAIK).

So lets move all the models which are only on the win8 blacklist because of
brightness issues to the use_native_backlight list, which is the smaller
hammer to use to solve the backlight issues.

Note: this is not tested on any of the affected models, this just seems like
the sensible thing to do.

Since commit 170269a9d3c0 (ACPI / video: Default to using native backlight
control on Windows 8 systems) in linux-next is effectively removing the black
list from video.c, I guess what you really would like to do would be to drop
the items from blacklist.c.  If so, please submit a patch to remove them on
top of commit 170269a9d3c0.

Right, the RFC was mostly for discussing what to do in case commit 170269a9d3c0
does not work out well and ends up being reverted (as this was tried before and
got reverted pretty quickly).

I'll send a patch just removing all the entries for -next for now, and I'll try
to remember that we need a patch like this RFC if we end up reverting.

OK, thanks!
