"PCI: designware: Add irq_create_mapping()" http://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/commit/?h=pci/host-exynos&id=904d0e7889933fb48d921c998fd1cabb3a9d6635 Best regards, Jingoo Han -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
