From: Nicolai Stange Subject: [PATCH RESEND v2 11/14] lib/mpi: mpi_read_raw_from_sgl(): purge redundant clearing of nbits Date: Mon, 21 Mar 2016 14:26:12 +0100 Message-ID: <1458566775-5239-12-git-send-email-nicstange@gmail.com> References: <1458566775-5239-1-git-send-email-nicstange@gmail.com> Cc: Tadeusz Struk , Michal Marek , Andrzej Zaborowski , Stephan Mueller , Arnd Bergmann , linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org, Nicolai Stange To: Herbert Xu , "David S. Miller" Return-path: In-Reply-To: <1458566775-5239-1-git-send-email-nicstange@gmail.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org In mpi_read_raw_from_sgl(), unsigned nbits is calculated as follows: nbits = nbytes * 8; and redundantly cleared later on if nbytes == 0: if (nbytes > 0) ... else nbits = 0; Purge this redundant clearing for the sake of clarity.
