Subject: Re: [PATCH] mtd: spinand: add support for Dosilicon DS35Q1GA/DS35M1GA
Hi Ahmed,
kernel test robot noticed the following build errors:
[auto build test ERROR on mtd/nand/next]
[also build test ERROR on linus/master next-20251208]
[cannot apply to v6.18]
[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
