Chen Fan (2):
pci: add an irq_invalid flag to specify the IRQ is not connected
i801_smbus: fix unavailable irq number 255 reported by BIOS
drivers/acpi/pci_irq.c| 10 ++
drivers/i2c/busses/i2c-i801.c | 5 +
include/linux/pci.h | 1
nd 254 are reserved."
So we add an irq_invalid flag to tell driver that the device wire
is not connected. then the driver could know whether it should call
request_irq().
