From 218d1cc1860c45b77f6814b44f6f0ffb9e40a82f Mon Sep 17 00:00:00 2001 From: Corentin LABBE Date: Fri, 26 Jan 2018 20:15:30 +0100 Subject: crypto: engine - Permit to enqueue all async requests The crypto engine could actually only enqueue hash and ablkcipher request. This patch permit it to enqueue any type of crypto_async_request.
