commit: 21038b0900d1b8728ec77d9286d7b0b57ca7b585 scsi: qla2xxx: Fix endianness annotations in header files
date: 2 months ago
config: x86_64-randconfig-s022-20200802 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-14) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-115-g5fc204f2-dirty
git checkout 21038b0900d1b8728ec77d9286d7b0b57ca7b585
# save the attached .config to linux build tree
make W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=x86_64
If you fix the issue, kindly add following tag as appropriate
