The pci_do_device_reset() function (called from pci_device_reset) clears the PCI_INTERRUPT_LINE config reg of devices on the bus but did this without taking wmask into account. We'll have a device model now that needs to set a constant value for this reg and this patch allows to do that without additional workaround in device emulation to reverse the effect of this PCI bus reset function.
