Subject: Re: [PATCH 2/3] lib/crypto: Initial implementation of Ascon-Hash256

Hi Rusydi,

kernel test robot noticed the following build errors:

[auto build test ERROR on ebiggers/libcrypto-next]
[also build test ERROR on ebiggers/libcrypto-fixes linus/master v6.19-rc1 next-20251215]
[cannot apply to herbert-cryptodev-2.6/master herbert-crypto-2.6/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
https://git-scm.com/docs/git-format-patch#_base_tree_information]
