From 92c8e4962054a6cf5171b3d7a3a77b799ca62c10 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 10 Apr 2013 15:59:58 +0200 Subject: [PATCH] irqchip: exynos: localize irq lookup for ATAGS The IRQ_SPI() macro is not available in the driver when building with sparse IRQs or multiplatform, so let's move all users of this into one function that we can leave out when building DT-only.
