Hi Seshu,

kernel test robot noticed the following build errors:

[auto build test ERROR on v6.11]
[also build test ERROR on next-20240927]
[cannot apply to linus/master]
[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]
