commit: 59000ffdca0f77c3f45fe7610510b17382fc8974 [4/17] platform/apple: Add new Apple Mac SMC driver
config: powerpc-allmodconfig (https://download.01.org/0day-ci/archive/20220817/202208170620.ruISFGG4-lkp@intel.com/config)
compiler: clang version 16.0.0 (https://github.com/llvm/llvm-project aed5e3bea138ce581d682158eb61c27b3cfdd6ec)
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 powerpc cross compiling tool for clang build
# apt-get install binutils-powerpc-linux-gnu
# https://github.com/AsahiLinux/linux/commit/59000ffdca0f77c3f45fe7610510b17382fc8974
git remote add asahilinux https://github.com/AsahiLinux/linux
git fetch --no-tags asahilinux bits/110-smc
git checkout 59000ffdca0f77c3f45fe7610510b17382fc8974
# save the config file
mkdir build_dir && cp config build_dir/.config
