Why?

The same reason as for commit 993e6f2fd.
I was asking just about the useless *return* statement...
Ah!
I did some investigation before whether using 'return' in empty void
functions or not.
static void can_dellink(struct net_device *dev, struct list_head *head);
and
static void can_dellink(struct net_device *dev, struct list_head *head)
{
return;
}
do the same job, right?
But the first one looks like a forward declaration and you would try to
find the 'implementing' function then.
Of course you can write less code and both implementations are correct -
but this representation makes it pretty clear that here's nothing to do :-)
