type in assignment (different base types)
Hi SrujanaChalla,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 83bdc7275e6206f560d247be856bceba3e1ed8f2
commit: 655ff1a1a727f9b83df317c4ad3b2f4a48f6206c crypto: marvell - create common Kconfig and Makefile for Marvell
date: 4 months ago
config: arm-randconfig-s031-20200730 (attached as .config)
compiler: arm-linux-gnueabi-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# apt-get install sparse
# sparse version: v0.6.2-98-g4932334a-dirty
git checkout 655ff1a1a727f9b83df317c4ad3b2f4a48f6206c
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=arm
If you fix the issue, kindly add following tag as appropriate
