Subject: crypto: caam - fix non-hmac hashes

From: Russell King <[email protected]>

commit a0118c8b2be9297aed8e915c60b4013326b256d4 upstream.

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)")
