Subject: Re: [PATCH v7 8/8] iio: adc: ad4851: add ad485x driver
Hi Antoniu,
kernel test robot noticed the following build errors:
[auto build test ERROR on jic23-iio/togreg]
[also build test ERROR on linus/master v6.12 next-20241128]
[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
