Subject: Re: [PATCH v2] mtd: rawnand: macronix: OTP access for MX30LFxG18AC
Hi Arseniy,
kernel test robot noticed the following build errors:
[auto build test ERROR on mtd/nand/next]
[also build test ERROR on linus/master v6.3 next-20230428]
[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
