Hi Laurent,

First bad commit (maybe != root cause):

tree:   git://linuxtv.org/pinchartl/media.git drm/du/compile-test
head:   e5afcf496f9bd487419c7ee0c258da75d0d1dae6
commit: 38c621b82b0e47d9fd0ce837b3c0f8c5c8156727 [11/12] drm/tegra: Enable COMPILE_TEST on all architectures
config: parisc-allyesconfig (attached as .config)
compiler: hppa-linux-gcc (GCC) 10.3.0
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 remote add pinchartl-media git://linuxtv.org/pinchartl/media.git
        git fetch --no-tags pinchartl-media drm/du/compile-test
        git checkout 38c621b82b0e47d9fd0ce837b3c0f8c5c8156727
        # save the attached .config to linux build tree
        COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-10.3.0 make.cross ARCH=parisc 

If you fix the issue, kindly add following tag as appropriate
