I just thought it falls under fbdev, as it's under drivers/video/ =3D). I don't have any particular "want" to take it through fbdev tree.

I'm happy if somebody wants to maintain the backlight side. In fact, I'd be happy if somebody would start restructuring it totally, it's rather messy. The link with fbdev should be removed, and some backlight drivers are actually panel drivers. However, perhaps Common Display Framework is required until it can be fully cleaned. So... For the time being, I'm fine with merging pwm-backlight via any tree that works best. I'm presuming here that backlight framework and fbdev (for the parts that are relevant for backlight) are not really being changed, so there shouldn't be conflicts.
