This first of all has absolutely nothing to do with your patch, it is
not eliminating an assignment from an if statement.

Second of all, this layout is absolutely intentional.

It makes it such that when new netlink attributed are added, the
patch to add them to this calculation is minimized to one line.

Therefore, please keep that semicolon on a line all by itself.
