From cb3078f35b16b5346a90317d2d4ce2a577429d8a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Horia=20Geant=C4=83?= Date: Mon, 29 Jan 2018 10:38:35 +0200 Subject: [PATCH] crypto: caam/qi - return -EBADMSG for ICV check failure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Crypto drivers are expected to return -EBADMSG in case of ICV check (authentication) failure. In this case it also makes sense to suppress the error message in the QI dequeue callback.
