Subject: [PATCH 0/2] ecdsa: Use ecc_digits_from_bytes to simplify code

Simplify two functions that were using temporary byte arrays for
converting too-short input byte arrays to digits. Use ecc_digits_from_bytes
since this function can now handle an input byte array that provides
less bytes than what a coordinate of a curve requires - the function
provides zeros for the missing (leading) bytes.

See: c6ab5c915da4 ("crypto: ecc - Prevent ecc_digits_from_bytes from reading too many bytes")

Regards,
   Stefan
