From fa0218ef733e6f247a1a3986e3eb12460064ac77 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Tue, 11 Sep 2018 10:44:03 -0700 Subject: misc: kgdbts: Fix restrict error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit kgdbts current fails when compiled with restrict: drivers/misc/kgdbts.c: In function ‘configure_kgdbts’: drivers/misc/kgdbts.c:1070:2: error: ‘strcpy’ source argument is the same as destination [-Werror=restrict] strcpy(config, opt); ^~~~~~~~~~~~~~~~~~~ As the error says, config is being used in both the source and destination. Refactor the code to avoid the extra copy and put the parsing closer to the actual location.
