From 3200a71207c7d4ec4e961c0ef7ac50361de30e9a Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 21 Jun 2015 21:10:58 +0200 Subject: [PATCH] irqchip/sunxi-nmi: 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.
