Subject: Re: [PATCH net-next v6 2/2] net: ethernet: Add driver for Sunplus
SP7021
Hi Wells,
I love your patch! Yet something to improve:
[auto build test ERROR on net/master]
[also build test ERROR on robh/for-next linus/master v5.18-rc1 next-20220405]
[cannot apply to net-next/master]
[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
