====================
pull request (net-next): ipsec-next 2014-07-30

This is the last pull request for ipsec-next before I'll be
off for two weeks starting on friday. David, can you please
take urgent ipsec patches directly into net/net-next during
this time?

1) Error handling simplifications for vti and vti6.
   From Mathias Krause.

2) Remove a duplicate semicolon after a return statement.
   From Christoph Paasch.
