Subjectdrivers/scsi/bnx2i/bnx2i_hwi.c:220:9: sparse: sparse: cast from restricted __le32
Hi Kefeng,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 61556703b610a104de324e4f061dc6cf7b218b46
commit: ed1ed4c0da5447c5e322481ce2ef9f03336c6ffb riscv: mmiowb: Fix implicit declaration of function 'smp_processor_id'
date: 9 months ago
config: riscv-randconfig-s031-20210209 (attached as .config)
compiler: riscv64-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross

# apt-get install sparse
# sparse version: v0.6.3-215-g0fb77bb6-dirty
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ed1ed4c0da5447c5e322481ce2ef9f03336c6ffb
git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout ed1ed4c0da5447c5e322481ce2ef9f03336c6ffb
# save the attached .config to linux build tree
