string is not a string literal (potentially insecure)
Hi Chris,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 88fe49249c99de14e543c632a46248d85411ab9e
commit: 70a2b431c36483c0c06e589e11c59e438cd0ac06 drm/i915/gt: Rename lrc.c to execlists_submission.c
date: 3 months ago
config: x86_64-randconfig-r034-20210314 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project dfd27ebbd0eb137c9a439b7c537bb87ba903efd3)
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
