From: Kenji Kaneshige Date: Fri, 22 Aug 2008 08:16:48 +0000 (+0900) Subject: PCI: pciehp: fix irq initialization X-Git-Tag: MMI-PSA29.97-13-9~31178^2~29 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7a10e32a1a7ae240fa3925c5727d224eba3e31d;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git PCI: pciehp: fix irq initialization Current pciehp driver gets irq number from pci_dev->irq. But because pciehp driver is a pci express port service driver, it should get irq number from pcie_device->irq.
