Subject: Re: [PATCH v1 1/1] usb: typec: stusb160x: Make use of
i2c_get_match_data()
Hi Andy,
kernel test robot noticed the following build errors:
[auto build test ERROR on usb/usb-testing]
[also build test ERROR on usb/usb-next usb/usb-linus linus/master v6.11 next-20240925]
[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]
