From: Eiichiro Oiwa <eiichiro.oiwa.nm@xxxxxxxxxxx> 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 <robert.moore@xxxxxxxxx> Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@xxxxxxxxx> Signed-off-by: Len Brown <len.brown@xxxxxxxxx> --- drivers/acpi/events/evrgnini.c | 13 ++++++------- 1 files changed, 6 insertions(+), 7 deletions(-) diff --git a/drivers/acpi/events/evrgnini.c b/drivers/acpi/events/evrgnini.c index 5b3c7a8..203d135 100644 --- a/drivers/acpi/events/evrgnini.c +++ b/drivers/acpi/events/evrgnini.c @@ -225,13 +225,12 @@ acpi_ev_pci_config_region_setup(acpi_han if (!
