This matches the existing behaviour, and in that regard this is fine,
and it probably won't matter in practice, but note that
shader_glsl_get_register_name() uses "reg->data_type", which isn't
necessarily the same as "data_type" here.

I think the usage of sprintf() is more problematic. That too matches
the existing code, but we should be using string_buffer_sprintf() for
this kind of thing.
