Subject[tip:x86/asm 2/2] drivers/scsi/mpt3sas/mpt3sas_base.c:3365:16: sparse: incorrect type in argument 1 (different base types)
tree:   https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/asm
head: 6469a0ee0a06b2ea1f5afbb1d5a3feed017d4c7a
commit: 6469a0ee0a06b2ea1f5afbb1d5a3feed017d4c7a [2/2] x86/io: Define readq()/writeq() to use 64-bit type
reproduce:
# apt-get install sparse
git checkout 6469a0ee0a06b2ea1f5afbb1d5a3feed017d4c7a
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
