Hi Christian,
kernel test robot noticed the following build errors:
[auto build test ERROR on atorgue-stm32/stm32-next]
[also build test ERROR on robh/for-next linus/master v6.11-rc3 next-20240812]
[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
