From d320b9a5bd85f6178cc3ed8b0a1a9960f2b5bc7b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@arndb.de> Date: Mon, 24 Oct 2016 17:33:18 +0200 Subject: [PATCH] x86/quirks: Hide maybe-uninitialized warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc -Wmaybe-uninitialized detects that quirk_intel_brickland_xeon_ras_cap uses uninitialized data when CONFIG_PCI is not set: arch/x86/kernel/quirks.c: In function ‘quirk_intel_brickland_xeon_ras_cap’: arch/x86/kernel/quirks.c:641:13: error: ‘capid0’ is used uninitialized in this function [-Werror=uninitialized] However, the function is also not called in this configuration, so we can avoid the warning by moving the existing #ifdef to cover it as well.
