Subject: [PATCH] crypto: inside-secure: Remove redundant DES ECB & CBC keysize check
Date: Wed, 31 Jul 2019 08:10:54 +0200 [thread overview]
Message-ID: <1564553454-25955-1-git-send-email-pvanleeuwen@verimatrix.com> (raw)
This patch removes a DES key size check that is redundant as it is already
performed by the crypto API itself due to min_keysize = max_keysize.
