Re: [PATCH 0/8] MR281: vkd3d-shader/tpf: Replace sm4 register structs with vkd3d-shader register structs, part 1.

[Giovanni Mascellani (＠giomasce)]

Giovanni Mascellani (@giomasce) commented about libs/vkd3d-shader/tpf.c:

If a valid `register_type_info` is returned, then it never has `VKD3DSPR_INVALID`, I think?
