[Patch Part1 v3 19/20] iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ

From: Jiang Liu
Date: Mon Oct 27 2014 - 04:14:49 EST


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.
