Subject: [RFC Part1 v1 18/18] iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ
Date: Thu, 11 Sep 2014 16:25:05 +0800 [thread overview]
Message-ID: <1410423905-26239-19-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1410423905-26239-1-git-send-email-jiang.liu@linux.intel.com>
Use helpers to access irq_cfg data structure associated with IRQ,
instead of accessing irq_data->chip_data directly. Later we could
rewrite those helpers to support hierarchy irqdomain.
