Hi Daniel,

FYI, the error/warning still remains.

commit: 333cff6c963fbc8b9820ca2b6a8b2e22a572cd43 [21/50] powercap/drivers/idle_inject: Specify idle state max latency
config: sh-allmodconfig (attached as .config)
compiler: sh4-linux-gcc (GCC) 9.3.0
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
        git checkout 333cff6c963fbc8b9820ca2b6a8b2e22a572cd43
        # save the attached .config to linux build tree
        COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=sh
