From 6cf02fcab1f6158c224fb00619f21556d8e5c4ea Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Sat, 7 Feb 2015 06:27:45 -0500 Subject: [PATCH] crypto: sahara - pass on error condition A failure of sahara_hw_descriptor_create() with -EINVAL due to scatter list out of bounds/invalid would not be reported back. This patch just passes on the -EINVAL so it is visible in sahara_queue_manage().
