Subject: [PATCH] ARM: mvebu: fix compilation warning on Armada 370 (i.e. non-SMP)
Date: Mon, 20 Jan 2014 21:14:13 +0100 [thread overview]
Message-ID: <87r48276ne.fsf@natisbad.org> (raw)
The following appears during compilation for an Armada 370 target
because 'irq_controller_lock' is used only when CONFIG_SMP is enabled:
drivers/irqchip/irq-armada-370-xp.c:62:8: warning: 'irq_controller_lock' defined but not used [-Wunused-variable]
Fix that warning by protecting declaration via an #ifdef.
Signed-off-by: Arnaud Ebalard <arno@natisbad.org>
