[patch 15/22] pinctrl: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc
From: Thomas Gleixner
Date: Mon Jul 13 2015 - 16:48:12 EST
From: Jiang Liu <jiang.liu@xxxxxxxxxxxxxxx>
Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.
