sparse: sparse: incorrect type in argument 2 (different address spaces)
Hi Arnd,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git master
head: b33bc2b878e05c5dd4e20682328c3addb4787ac9
commit: 6d97985072dc270032dc7a08631080bfd6253e82 [391/455] isdn: move capi drivers to staging
reproduce:
# apt-get install sparse
# sparse version: v0.6.1-rc1-7-g2b96cd8-dirty
git checkout 6d97985072dc270032dc7a08631080bfd6253e82
make ARCH=x86_64 allmodconfig
make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag
