The original code defines a named object for the resource template but then returns the resource template object itself; the resulted output is like below: Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (RBUF, ResourceTemplate () { WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode, 0x0000, // Granularity 0x0000, // Range Minimum 0x00FF, // Range Maximum 0x0000, // Translation Offset 0x0100, // Length ,, ) ...... }) Return (ResourceTemplate () { WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode, 0x0000, // Granularity 0x0000, // Range Minimum 0x00FF, // Range Maximum 0x0000, // Translation Offset 0x0100, // Length ,, ) ...... }) } So the named object "RBUF" is actually useless. The more natural way is to return RBUF instead, or simply drop RBUF definition. Choose the latter one to simplify the code. Signed-off-by: Heyi Guo <guoheyi@huawei.com> Reviewed-by: Michael S.
