I think a better Contact might simply be: Contact: dri-devel@xxxxxxxxxxxxxxxxxxxxx > +Description: > + (WO) Write to the backlight mapping mode. The backlight current > + can be mapped for either exponential (value "0") or linear > + mapping modes (default). The ambiguity of meaning w.r.t. linear or exponential is something of a thorn in the side of backlight... and so long as that ambiguity remains this control is something the userspace may want to poke (albeit only once during boot). If you repost with an updated contact then please add my ack for this patch: Acked-by: Daniel Thompson <daniel.thompson@xxxxxxxxxx> Daniel. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
