nb/intel/i945: Remove redundant use of ACPI offset operator
IASL version 20180927 and greater, detects Unnecessary/redundant uses of
the Offset() operator within a Field Unit list.
It then sends a remark "^ Unnecessary/redundant use of Offset"
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
