[kernel test robot <lkp@intel.com>]

Hi Andrew,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on drm-misc/drm-misc-next]
[also build test ERROR on drm-intel/for-linux-next drm-tip/drm-tip linus/master v6.0-rc2 next-20220824]
[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
