Subject: drivers/clk/clk-hsdk-pll.c:407:24: sparse: expected void
Hi Stephen,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 0bddd227f3dc55975e2b8dfa7fc6f959b062a2c7
commit: bbd7ffdbef6888459f301c5889f3b14ada38b913 clk: Allow the common clk framework to be selectable
date: 9 weeks ago
config: openrisc-randconfig-s031-20200710 (attached as .config)
compiler: or1k-linux-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: v0.6.2-37-gc9676a3b-dirty
git checkout bbd7ffdbef6888459f301c5889f3b14ada38b913
# 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=openrisc
If you fix the issue, kindly add following tag as appropriate
