From: Cyrille Pitchen Subject: [PATCH next 1/2] crypto: atmel-sha: fix missing "return" instructions Date: Thu, 9 Feb 2017 17:51:20 +0100 Message-ID: References: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: Cyrille Pitchen , dan.carpenter@oracle.com, linux-crypto@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org To: , , Return-path: In-Reply-To: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org List-Id: linux-crypto.vger.kernel.org This patch fixes a previous patch: "crypto: atmel-sha - update request queue management to make it more generic". Indeed the patch above should have replaced the "return -EINVAL;" lines by "return atmel_sha_complete(dd, -EINVAL);" but instead replaced them by a simple call of "atmel_sha_complete(dd, -EINVAL);". Hence all "return" instructions were missing.
