Not passing any modifiers is the same as explicitly passing INVALID, both of which mean 'the driver will figure it out somehow'; that driver-specific determination is not the same as explicit LINEAR. > > (I cannot regret enough that INVALID is not 0.)

I'll amend my changes to explicitly handle INVALID. > > Cheers, > Daniel _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
