From 5b29264c659c31bada65582005d99adb3bb41fea Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 4 Jun 2015 12:13:20 +0800 Subject: [PATCH] irqchip: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc.
