Subject: Re: [PATCH 4/4] tty: serial: 8250: Add support for MOXA PCIe boards
to switch interface between RS422/RS485
Hi Crescent,
kernel test robot noticed the following build errors:
[auto build test ERROR on tty/tty-testing]
[also build test ERROR on tty/tty-next tty/tty-linus usb/usb-testing usb/usb-next usb/usb-linus linus/master v6.6-rc4 next-20230929]
[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
