It's in linux-next I think:
commit 2fd2a82ccbfc106aec314db6c4bda5e24fd32a22
Author: Stefan Berger <stefanb@...ux.ibm.com>

    crypto: ecdsa - Use ecc_digits_from_bytes to create hash digits array
    
    Since ecc_digits_from_bytes will provide zeros when an insufficient number
    of bytes are passed in the input byte array, use it to create the hash
    digits directly from the input byte array. This avoids going through an
    intermediate byte array (rawhash) that has the first few bytes filled with
    zeros.
