Subject: [RFC v1 01/25] ARM, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc
Date: Wed, 20 May 2015 17:59:49 +0800 [thread overview]
Message-ID: <1432116013-25902-2-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1432116013-25902-1-git-send-email-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.
