From c26819900036f5b91608051a0fc7c76f6b4ffc7b Mon Sep 17 00:00:00 2001 From: Herbert Xu <herbert@gondor.apana.org.au> Date: Wed, 1 Feb 2017 22:17:39 +0800 Subject: crypto: aesni - Fix failure when pcbc module is absent MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When aesni is built as a module together with pcbc, the pcbc module must be present for aesni to load. However, the pcbc module may not be present for reasons such as its absence on initramfs. This patch allows the aesni to function even if the pcbc module is enabled but not present.
