Subjectdrivers/gpu/drm/amd/amdgpu/jpeg_v2_0.c:442:6: warning: no previous prototype for function 'jpeg_v2_0_dec_ring_insert_start'
tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 1b5044021070efa3259f3e9548dc35d1eb6aa844
commit: 6ac27241106bc946bd50032f4cd96899c6a6fe69 drm/amdgpu: add JPEG v2.0 function supports
date: 7 months ago
config: s390-randconfig-r004-20200617 (attached as .config)
compiler: clang version 11.0.0 (https://github.com/llvm/llvm-project 487ca07fcc75d52755c9fe2ee05bcb3b6eeeec44)
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install s390 cross compiling tool for clang build
# apt-get install binutils-s390-linux-gnu
git checkout 6ac27241106bc946bd50032f4cd96899c6a6fe69
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=s390

If you fix the issue, kindly add following tag as appropriate
