Or we could specify that we support 8-byte accesses and expand the switch to include it. Neither is terribly pressing at this point, so I'll leave that for some future work. > Reviewed-by: Longpeng <longpeng2@huawei.com> Thanks!

vfio_rom_read() relies on memcpy() doing the logically correct thing, ie. safely copying zero bytes from a NULL pointer when rom_size is zero, rather than the spec definition, which is undefined when the source or target pointers are NULL. Resolve this by wrapping the call in the condition expressed previously by the ternary. Additionally, we still use @val to fill data based on the provided @size regardless of mempcy(), so we should initialize @val rather than @data.
