4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Horia Geantă <horia.gea...@nxp.com>
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
