From 741ff9661337231233cd675df7726ffafe13c960 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 21 Jun 2015 21:10:49 +0200 Subject: [PATCH] irqchip/exynos-combiner: Consolidate chained IRQ handler install/remove Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one.
