Subject: [Patch v3 25/36] sh, irq: Use access helper irq_data_get_affinity_mask()
Date: Mon, 01 Jun 2015 08:05:34 +0000	[thread overview]
Message-ID: <1433145945-789-26-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1433145945-789-1-git-send-email-jiang.liu@linux.intel.com>

Use access helper irq_data_get_affinity_mask() to hide implementation
details of struct irq_desc.
