We could redef
we don't have right now, that needs to be added. And for any extra level of macro we need to redef INTEL_VGA_DEVICE nonetheless because it expands to "{ ... }". I don't know any cpp trick to remove the extra fields if it keeps the braces. > INTEL_VGA_DEVICE() and INTEL_QUANTA_VGA_DEVICE() but one extra level of > macro would be easier for future. So... I don't see a way out except to redef it.
