Subject: [PATCH AUTOSEL 5.5 216/542] x86/mce/therm_throt: Mark throttle_active_work() as __maybe_unused
Date: Fri, 14 Feb 2020 10:43:28 -0500
Message-ID: <20200214154854.6746-216-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>

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")
