From 286233e604d79f0c7fa04abec2180d5d89a74749 Mon Sep 17 00:00:00 2001 From: Horia Geanta Date: Fri, 10 May 2013 15:08:39 +0300 Subject: crypto: caam - fix inconsistent assoc dma mapping direction req->assoc is dma mapped BIDIRECTIONAL and unmapped TO_DEVICE. Since it is read-only for the device, use TO_DEVICE both for mapping and unmapping.
