commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream.
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
