Hi Jianhua,

kernel test robot noticed the following build errors:

[auto build test ERROR on media-tree/master]
[also build test ERROR on linuxtv-media-stage/master sailus-media-tree/master linus/master v6.11-rc2 next-20240807]
[cannot apply to sailus-media-tree/streams]
[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
