My gcc 4.8.2 doesn't complain the change, see below:

ming@ming:~/ming/linux$ gcc --version
gcc (Ubuntu/Linaro 4.8.2-19ubuntu1) 4.8.2

ming@ming:~/ming/linux$
ming@ming:~/ming/linux$ vim block/blk-mq.c
ming@ming:~/ming/linux$ ./build
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CC      block/blk-mq.o
  CHK     kernel/config_data.h
