From 1b008eedb0afcc7afa26f17ce16069789f8ce5ba Mon Sep 17 00:00:00 2001 From: =?utf8?q?Horia=20Geant=C4=83?= Date: Wed, 9 Nov 2016 10:46:17 +0200 Subject: [PATCH] crypto: caam - remove unused command from aead givencrypt MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit REG3 no longer needs to be updated, since it's not used after that. This shared descriptor command is a leftover of the conversion to AEAD interface.
