From 65b2728145771b0df18f85303b8ae152cd53f2de Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 1 Feb 2021 11:13:21 -0700 Subject: [PATCH] coresight: cti: Reduce scope for the variable 'cs_fwnode' in cti_plat_create_connection() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A local variable was used only within an else branch. Thus move the definition for the variable “cs_fwnode” into the corresponding code block. This issue was detected by using the Coccinelle software.
