commit: d5c65159f2895379e11ca13f62feabe93278985d ath11k: driver for Qualcomm IEEE 802.11ax devices
date: 10 months ago
config: x86_64-randconfig-a015-20200910 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project 0a5dc7effb191eff740e0e7ae7bd8e1f6bdb3ad9)
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 d5c65159f2895379e11ca13f62feabe93278985d
# save the attached .config to linux build tree
