x86: pci: acpi: reorder Device's _DSM method
align _DSM method in empty slot descriptor with
a populated slot position.
Expected change:
+ Device (SE8)
+ {
+ Name (_ADR, 0x001D0000) // _ADR: Address
+ Name (ASUN, 0x1D)
Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method
{
Local0 = Package (0x02)
{
BSEL,
ASUN
}
Return (PDSM (Arg0, Arg1, Arg2, Arg3, Local0))
}
- }
- Device (SE8)
- {
- Name (_ADR, 0x001D0000) // _ADR: Address
- Name (ASUN, 0x1D)
Name (_SUN, 0x1D) // _SUN: Slot User Number
Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device
{
PCEJ (BSEL, _SUN)
}
+ }
i.e. put _DSM right after ASUN, with _SUN/_EJ0 following it.
that will eliminate contextual changes (causing test failures)
when follow up patches merge code generating populated and empty
slots descriptors.
