Subject: [RFC v1 11/25] keystone, irq: Use irq_data_get_xxx() to avoid redundant lookup of irq_data
Date: Wed, 20 May 2015 17:59:59 +0800 [thread overview]
Message-ID: <1432116013-25902-12-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_data_get_xxx() to avoid redundant lookup of irq_data while we
already have a pointer to corresponding irq_data.
