Hi Chris,
kernel test robot noticed the following build warnings:
[auto build test WARNING on robh/for-next]
[also build test WARNING on tip/timers/core tip/irq/core tip/smp/core linus/master v6.10-rc5 next-20240625]
[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]
