Subject: Re: [PATCH] crypto: virtio - Less function calls in
__virtio_crypto_akcipher_do_req() after error detection
Hi Markus,
kernel test robot noticed the following build errors:
[auto build test ERROR on herbert-cryptodev-2.6/master]
[also build test ERROR on herbert-crypto-2.6/master linus/master v6.7-rc7 next-20231222]
[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
