+
+commit 2dd453168643d9475028cd867c57e65956a0f7f9 upstream.
+
+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.
