Subject: [patch 05/11] ARM, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc
Date: Mon, 13 Jul 2015 20:29:06 -0000 [thread overview]
Message-ID: <20150713090936.341427183@linutronix.de> (raw)
In-Reply-To: 20150713090726.316699641@linutronix.de
From: Jiang Liu <jiang.liu@linux.intel.com>
Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.
