SubjectRe: [PATCH] target: make config_item_type const
Hi Bhumika,

[auto build test WARNING on target/master]
[also build test WARNING on v4.14-rc4 next-20171009]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Bhumika-Goyal/target-make-config_item_type-const/20171013-120027
base: https://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master
config: x86_64-randconfig-x012-201741 (attached as .config)
