From: Jiang Liu Date: Thu, 4 Jun 2015 04:13:19 +0000 (+0800) Subject: ARM, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f575398bff9ae08086b345ecf724568be53818ee;p=deliverable%2Flinux.git ARM, irq: 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.
