From a84277bf3efcc7bb5b5a5eec62de5c134cb47ee5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 5 Jun 2018 13:43:34 +0200 Subject: irqchip/stm32: Fix non-SMP build warning A CONFIG_SMP=n build emits a harmless compile-time warning: drivers/irqchip/irq-stm32-exti.c:495:12: error: 'stm32_exti_h_set_affinity' defined but not used [-Werror=unused-function] The #ifdef is inconsistent here, and it's better to use an IS_ENABLED() check that lets the compiler silently drop that function.
