Mika Westerberg 7282059489 ACPI / hotplug / PCI: Relax the checking of _STA return values ... The ACPI specification (ACPI 5.0A, Section 6.3.7) says: _STA may return bit 0 clear (not present) with bit 3 set (device is functional). This case is used to indicate a valid device for which no device driver should be loaded (for example, a bridge device.) Children of this device may be present and valid. OSPM should continue enumeration below a device whose _STA returns this bit combination. Evidently, some BIOSes follow that and return 0x0A from _STA, which causes problems to happen when they trigger bus check or device check notifications for those devices too. Namely, ACPIPHP thinks that they are gone and may drop them, for example, if such a notification is triggered during a resume from system suspend. To fix that, modify ACPICA to regard devies as present and functioning if _STA returns both the ACPI_STA_DEVICE_ENABLED and ACPI_STA_DEVICE_FUNCTIONING bits set for them.
