From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Thu, 12 Nov 2015 15:20:16 +0100 Subject: [PATCH] ARM64: mark cpus_have_hwcap as __maybe_unused Message-ID: <5369626.MJXv4CTaxt@wuerfel> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org cpus_have_hwcap() is defined as a 'static' function an only used in one place that is inside of an #ifdef, so we get a warning when the only user is disabled: arch/arm64/kernel/cpufeature.c:699:13: warning: 'cpus_have_hwcap' defined but not used [-Wunused-function] This marks the function as __maybe_unused, so the compiler knows that it can drop the function definition without warning about it.
