In the commit message you said that this patch enables CCS_E for winsys
buffers. I don't see how that happens as we check for is_scanout here (which
gets set by intel_miptree_create_layout() by
intel_update_winsys_renderbuffer_miptree() passing MIPTREE_LAYOUT_FOR_SCANOUT).
Other than that this looks good:
