[PATCH 3/5] crypto: remove RIPE-MD 320 hash algorithm

[Ard Biesheuvel <ardb@kernel.org>]

RIPE-MD 320 is never referenced anywhere in the kernel, and unlikely
to be depended upon by userspace via AF_ALG. So let's remove it

-	  RIPEMD-320 is an optional extension of RIPEMD-160 with a
-	  320 bit hash. It is intended for applications that require
-	  longer hash-results, without needing a larger security level
-	  (than RIPEMD-160).
