crypto: tcrypt - fix ghash-generic speed test
ghash is a keyed hash algorithm, thus setkey needs to be called. Otherwise the following error occurs: $ modprobe tcrypt mode=318 sec=1 testing speed of async ghash-generic (ghash-generic) tcrypt: test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): tcrypt: hashing failed ret=-126 Cc: <stable@vger.kernel.org> # 4.6+ Fixes: 0660511c0bee ("crypto: tcrypt - Use ahash") Tested-by: Franck Lenormand <franck.lenormand@nxp.com> Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
