[PATCH] depend on BACKLIGHT_CLASS_DEVICE for more devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



playing around a little bit with this, I think the original "select
BACKLIGHT_CLASS_DEVICE" is fine. Atm we kind of have this weird mix of
drivers selecting and others depending on it. We could of course convert
everything over to depend, and break those cycling dependency issues with
this.

Anyway this change on top of my initial patch is enough to make Kconfig
happy and has the advantage of not having to mess with the deps of nouveau
too much.
