===============
[ Upstream commit a0118c8b2be9297aed8e915c60b4013326b256d4 ]
Since 6de62f15b581 ("crypto: algif_hash - Require setkey before
accept(2)"), the AF_ALG interface requires userspace to provide a key
to any algorithm that has a setkey method. However, the non-HMAC
algorithms are not keyed, so setting a key is unnecessary.
Fix this by removing the setkey method from the non-keyed hash
algorithms.
Fixes: 6de62f15b581 ("crypto: algif_hash - Require setkey before accept(2)")
