SubjectRe: [PATCH] staging: rts5208: Replace embedded function names with "%s: ", __func__
Hi Gaurav,

[auto build test ERROR on staging/staging-testing]
[also build test ERROR on v4.12 next-20170706]
[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/Gaurav-Pathak/staging-rts5208-Replace-embedded-function-names-with-s-__func__/20170706-131957
config: i386-randconfig-c0-07070124 (attached as .config)
compiler: gcc-4.9 (Debian 4.9.4-2) 4.9.4
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):
