Subject: linux-next: build failure after merge of the crypto tree

Hi all,

After merging the crypto tree, today's linux-next build (powerpc
allyesconfig) failed like this:

net/ipv4/tcp_ao.c: In function 'tcp_ao_key_alloc':
net/ipv4/tcp_ao.c:1536:13: error: implicit declaration of function 'crypto_ahash_alignmask'; did you mean 'crypto_ahash_alg_name'? [-Werror=implicit-function-declaration]
 1536 |         if (crypto_ahash_alignmask(tfm) > TCP_AO_KEY_ALIGN) {
      |             ^~~~~~~~~~~~~~~~~~~~~~
      |             crypto_ahash_alg_name

Caused by commit

  0f8660c82b79 ("crypto: ahash - remove crypto_ahash_alignmask")

interacting with commit

  4954f17ddefc ("net/tcp: Introduce TCP_AO setsockopt()s")

from the net-next tree.

I have applied the following merge resolution patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Mon, 30 Oct 2023 15:54:37 +1100
Subject: [PATCH] fix up for "crypto: ahash - remove crypto_ahash_alignmask"
