From: Arnd Bergmann Date: Tue, 23 Feb 2016 14:06:39 +0000 (+0100) Subject: ARM: mvebu: mark mvebu_hwcc_pci_nb as __maybe_unused X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60f23952317a34e8d41c22a6058dcb7bdaf91b96;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: mvebu: mark mvebu_hwcc_pci_nb as __maybe_unused The coherency notifier block is only used when CONFIG_PCI is enabled, otherwise we get a warning: arch/arm/mach-mvebu/coherency.c:110:30: warning: 'mvebu_hwcc_pci_nb' defined but not used [-Wunused-variable] There is no nice way to use an if(IS_ENABLED()) check here to let the compiler know that it might be used, so let's mark the structure as __maybe_unused.
