From 19e61d41404fe4094c2d54943dbf883d9bbca864 Mon Sep 17 00:00:00 2001 From: Arnaud Ebalard Date: Mon, 20 Jan 2014 22:52:05 +0100 Subject: ARM: mvebu: fix compilation warning on Armada 370 (i.e. non-SMP) 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 moving declaration of 'irq_controller_lock' inside existing #ifdef.
