Hi Stanley,
kernel test robot noticed the following build warnings:
[auto build test WARNING on usb/usb-testing]
[also build test WARNING on usb/usb-next usb/usb-linus robh/for-next linus/master v6.4-rc6 next-20230614]
[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
