This is not relevant for this patchset.

With https://patchwork.freedesktop.org/patch/534745/?series=116851&rev=2 
in place, VIG_SBLK and VIG_SBLK_ROT should also stop using num. But 
let's probably take another step forward and drop both arguments and use 
just a single instance of sblk per platform. I'll send a patch for it.
