drivers/wwan/fm: Use correct GUID for DmaProperty in ACPI _DSD
Use correct GUID for DmaProperty in ACPI _DSD.
Reference:
https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports
Before:
Name (_DSD, Package (0x02) // _DSD: Device-Specific Data
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /* Device Properties for _DSD */,
Package (0x01)
{
Package (0x02)
{
"DmaProperty",
One
}
}
})
After:
Name (_DSD, Package (0x02) // _DSD: Device-Specific Data
{
ToUUID ("70d24161-6dd5-4c9e-8070-705531292865"),
Package (0x01)
{
Package (0x02)
{
"DmaProperty",
One
}
}
})
BUG=b:259716145
TEST=Verified the new GUID is reflected in ACPI SSDT at runtime.
