From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Subject: [PATCH 1/9] um/drivers/vector_user: Delete unnecessary code in user_init_raw_fds() From: SF Markus Elfring References: Message-ID: Date: Sun, 11 Mar 2018 16:16:20 +0100 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=utf-8 Content-Language: en-GB Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org To: user-mode-linux-devel@lists.sourceforge.net, Anton Ivanov , Jeff Dike , Richard Weinberger Cc: user-mode-linux-user@lists.sourceforge.net, kernel-janitors@vger.kernel.org, LKML List-ID: From: Markus Elfring Date: Sun, 11 Mar 2018 11:36:18 +0100 * One condition check could never be reached with a non-null pointer at the end of this function. Thus remove the corresponding statement. * Delete an initialisation for the local variable "result" which became unnecessary with this refactoring.
