Subject: crypto: tcrypt - Remove unused poly1305 support
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bfc11a84e08c5945f0ddefbb8058402a7f32819d;p=thirdparty%2Flinux.git

crypto: tcrypt - Remove unused poly1305 support

Since the crypto_shash support for poly1305 was removed, the tcrypt
support for it is now unused as well.  Support for benchmarking the
kernel's Poly1305 code is now provided by the poly1305 kunit test.
