Hi Christophe,
First bad commit (maybe != root cause):

head: 1140ab592e2ebf8153d2b322604031a8868ce7a5
commit: eacf4c0202654adfa94bbb17b5c5c77c0be14af8 powerpc: Enable OPTPROBES on PPC32
date: 3 weeks ago
config: powerpc-randconfig-r033-20210511 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project

A clang issue ?
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
#

git remote add linus
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout eacf4c0202654adfa94bbb17b5c5c77c0be14af8
# save the attached .config to linux build tree

That's a 'static inline', shouldn't generate an 'unused function'
warning.
