From db1ae0314f47e88ae06679270adf17ffa245afd4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 10 Dec 2019 21:39:13 +0100 Subject: [PATCH] x86/mce/therm_throt: Mark throttle_active_work() as __maybe_unused throttle_active_work() is only called if CONFIG_SYSFS is set, otherwise we get a harmless warning: arch/x86/kernel/cpu/mce/therm_throt.c:238:13: error: 'throttle_active_work' \ defined but not used [-Werror=unused-function] Mark the function as __maybe_unused to avoid the warning.
