From 16b84e5a505c790538e534ad8dfda9c288691e40 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 19 Sep 2013 16:44:55 -0500 Subject: of/irq: Create of_irq_parse_and_map_pci() to consolidate arch code. Several architectures open code effectively the same code block for finding and mapping PCI irqs. This patch consolidates it down to a single function.
