From a9786091126233cf1333d23999bf07bdd0818486 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 27 Oct 2014 16:12:07 +0800 Subject: [PATCH] x86, irq: Use helpers to access irq_cfg data structure associated with IRQ Use helpers to access irq_cfg data structure associated with IRQ, instead of accessing irq_data->chip_data directly. Later we can rewrite those helpers to support hierarchy irqdomain.
