From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit db1ae0314f47e88ae06679270adf17ffa245afd4 ]
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.
Fixes: f6656208f04e ("x86/mce/therm_throt: Optimize notifications of thermal throttle")
