From 0d9c68a9bfc7259f847704f28c64549fc4078aa2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Antoine=20T=C3=A9nart?= Date: Thu, 1 Jun 2017 21:39:02 +0200 Subject: [PATCH] crypto: sun4i-ss - add the CRYPTO_ALG_KERN_DRIVER_ONLY flag The CRYPTO_ALG_KERN_DRIVER_ONLY flag is set for hardware accelerated ciphers accessible through a kernel driver only. This is the case for ciphers exposed by the sun4i-ss driver. This patch sets this flag.
