ACPICA: Fix incorrect handling of PCI Express Root Bridge _HID

I could not get correct PCI Express bus number from the structure of acpi_object_extra. I always get zero as bus number regardless of bus location. I found that there is incorrect comparison with _HID (PNP0A08) in acpi/events/evrgnini.c and PCI Express _BBN method always fail. Therefore, we always get zero as PCI Express bus number. http://bugzilla.kernel.org/show_bug.cgi?id=7145 Signed-off-by: Bob Moore <[email protected]> Signed-off-by: Alexey Starikovskiy <[email protected]> Signed-off-by: Len Brown <[email protected]>
