Hi Andy,
kernel test robot noticed the following build errors:
[auto build test ERROR on drm-intel/for-linux-next]
[also build test ERROR on drm-intel/for-linux-next-fixes linus/master v6.6 next-20231103]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
