Hi Chris,
kernel test robot noticed the following build errors:
[auto build test ERROR on wsa/i2c/for-next]
[also build test ERROR on linus/master v6.6-rc6 next-20231020]
[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
