From 867d898ccf50ef095b95c403d7dc809c188b14e2 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sun, 17 Nov 2013 19:00:22 +0100 Subject: [PATCH] acpi-build: Fix compiler warning (missing gnu_printf format attribute) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc 4.8.2 reports this warning when extra warnings are enabled (-Wextra): CC m68k-softmmu/hw/m68k/mcf5206.o hw/i386/acpi-build.c: In function ‘build_append_nameseg’: hw/i386/acpi-build.c:294:5: error: function might be possible candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format] g_string_vprintf(s, format, args); ^ When this warning is fixed, there is a new compiler warning: CC i386-softmmu/hw/i386/acpi-build.o hw/i386/acpi-build.c: In function ‘build_append_notify’: hw/i386/acpi-build.c:632:5: error: format not a string literal and no format arguments [-Werror=format-security] build_append_nameseg(method, name); ^ This is fixed here, too.
