From 5663bb27dec1a2bfaf9d92e3685834b91a36a5a3 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 4 Jun 2015 12:13:16 +0800 Subject: pinctrl: 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.
