Hi Luis,
[auto build test WARNING on scsi/for-next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]
url: https://github.com/0day-ci/linux/commits/Luis-de-Bethencourt/scsi-kconfig-When-possible-compile-drivers-with-COMPILE_TEST/20151015-051558
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
