From 2dd453168643d9475028cd867c57e65956a0f7f9 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 10 Sep 2018 16:20:14 -0700 Subject: [PATCH] kgdboc: Fix restrict error MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There's an error when compiled with restrict: drivers/tty/serial/kgdboc.c: In function ‘configure_kgdboc’: drivers/tty/serial/kgdboc.c:137:2: error: ‘strcpy’ source argument is the same as destination [-Werror=restrict] strcpy(config, opt); ^~~~~~~~~~~~~~~~~~~ As the error implies, this is from trying to use config as both source and destination. Drop the call to the function where config is the argument since nothing else happens in the function.
