Subject: [PATCH] ARM: imx: hide unused variable in #ifdef
Date: Tue, 10 Jan 2017 13:19:05 +0100 [thread overview]
Message-ID: <20170110130154.2994705-1-arnd@arndb.de> (raw)
A bugfix added a new local variable that is only used inside of an #ifdef
section, and unused if CONFIG_PERF_EVENTS is disabled:
arch/arm/mach-imx/mmdc.c:63:25: warning: 'cpuhp_mmdc_state' defined but not used [-Wunused-variable]
This moves the variable down inside that same ifdef.
Fixes: a051f220d6b9 ("ARM/imx/mmcd: Fix broken cpu hotplug handling")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
