Hi Clément,
kernel test robot noticed the following build errors:
[auto build test ERROR on linus/master] [also build test ERROR on v6.6-rc3 next-20230928] [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 https://git-scm.com/docs/git-format-patch#_base_tree_information]
