sb/intel/i82801gx: Remove unnecessary/redundant ACPI offset operator
Using ACPICA version 20180927 or greater, IASL detects Unnecessary/redundant
uses of the Offset() operator within a Field Unit list.
It then sends a remark "^ Unnecessary/redundant use of Offset".
Offsets refer to the current offset are unnecessary.
example:
OperationRegion (OPR1, SystemMemory, 0x100, 0x100)
Field (OPR1)
{
Offset (0), // Never needed
FLD1, 32,
Offset (4), // Redundant, offset is already 4 (bytes)
FLD2, 8,
Offset (64), // OK use of Offset.
FLD3, 16,
}
We will have those remarks:
dsdt.asl 14: Offset (0),
Remark 2158 - ^ Unnecessary/redundant use of Offset
operator
dsdt.asl 16: Offset (4),
Remark 2158 - ^ Unnecessary/redundant use of Offset
operator
