Hi Uma,

kernel test robot noticed the following build errors:

[auto build test ERROR on next-20251201]
[also build test ERROR on linus/master v6.18]
[cannot apply to drm-xe/drm-xe-next drm-intel/for-linux-next drm-intel/for-linux-next-fixes drm-tip/drm-tip v6.18 v6.18-rc7 v6.18-rc6]
[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
