It was. Before when wanting two invocations of DEV_INFO_FLAGS, you had
to define the same macros twice (DEV_INFO_FLAG/DEV_INFO_SEP), so to be
defensive about that #undef was added after DEV_INFO_FLAGS.

Now DEV_INFO_FOR_EACH_FLAG() takes the macro/sep to apply to each flag so
you can leave the macro defined, the second invocation will define its
own transformation (or reuse an existing one).
