From 2a4fe14bc8da0af53076fa90ac34738c7b55fc3b Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 21 Jun 2016 11:20:29 +0100 Subject: irqchip/exynos-combiner: Fix usage of __raw IO Fix the use of __raw IO accessors when the readl/writel_relaxed are better. This should fix issues if the kernel is running as big endian.
