commit: 6cb9c86b3595f9aa862d1c59b22d8bb2a7f8b0de [4/4] UPSTREAM: drm/i915: Do .init_clock_gating() earlier to avoid it clobbering watermarks
config: x86_64-randconfig-a012-20200806 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project 076b120bebfd727b502208601012a44ab2e1028e)
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 x86_64 cross compiling tool for clang build
# apt-get install binutils-x86-64-linux-gnu
git checkout 6cb9c86b3595f9aa862d1c59b22d8bb2a7f8b0de
# save the attached .config to linux build tree
