Re: [PATCH net-next 04/14] gtp: udp recv clean up

Hi Tom,

[auto build test ERROR on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Tom-Herbert/gtp-Additional-feature-support/20170919-143920
config: i386-randconfig-x016-201738 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

Note: the linux-review/Tom-Herbert/gtp-Additional-feature-support/20170919-143920 HEAD 737a09b8f9cd56706d01703d17523b0fea907f41 builds fine.
