Subject: drivers/clk/clk-divider.c:39:17: sparse: sparse: incorrect type in
argument 1 (different base types)
Hi Stephen,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 64677779e8962c20b580b471790fe42367750599
commit: bbd7ffdbef6888459f301c5889f3b14ada38b913 clk: Allow the common clk framework to be selectable
date: 7 weeks ago
config: alpha-randconfig-s032-20200621 (attached as .config)
compiler: alpha-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-rc2-13-gc59158c8-dirty
git checkout bbd7ffdbef6888459f301c5889f3b14ada38b913
# save the attached .config to linux build tree
make W=1 C=1 ARCH=alpha CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag as appropriate
