(FYI, Dave has pointed out and fixed up this this but anyway,)
My fault... Here's the updated version. It is available at the same URL.
I'll be more careful in the future.

commit 6dabb77fd82cd927727d5fb8136eff2e123910f5
Author: YOSHIFUJI Hideaki <[EMAIL PROTECTED]>
Date: Thu Aug 24 23:18:12 2006 +0900
[IPV6] MIP6: Several obvious clean-ups.
- Remove redundant code. Pointed out by Brian Haley <[EMAIL PROTECTED]>.
- Unify code paths with/without CONFIG_IPV6_MIP.
- Use NIP6_FMT for IPv6 address textual presentation.
- Fold long line. Pointed out by David Miller <[EMAIL PROTECTED]>.
