From: Fabio Baltieri Subject: [PATCH 5/6] crypto: ux500: use dmaengine_prep_slave_sg API Date: Tue, 25 Jun 2013 10:54:48 +0200 Message-ID: <1372150489-25594-6-git-send-email-fabio.baltieri@linaro.org> References: <1372150489-25594-1-git-send-email-fabio.baltieri@linaro.org> Cc: linux-crypto@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, Linus Walleij , Lee Jones , Fabio Baltieri To: Herbert Xu Return-path: In-Reply-To: <1372150489-25594-1-git-send-email-fabio.baltieri@linaro.org> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org Use dmaengine_prep_slave_sg inline function instead of going through the structures manually.
