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.

According to ACPI spec, _ADR should be used for device on a bus that
has a standard enumeration algorithm, but not for device which is on
system bus and must be enumerated by OSPM. And it is not recommended
to contain both _HID and _ADR in a single device.
See ACPI 6.3, section 6.1, top of page 343:
A device object must contain either an _HID object or an _ADR object,
but should not contain both.

Currently that is 10.14 and 10.15. We also may work on older versions, but

In commit 50290c002c in mid-2019 we introduced some uses of
CLOCK_MONOTONIC which incidentally broke compilation for pre-10.12 OSX
versions (see LP:1861551). We don't intend to fix that, so we might
as well drop the code in ui/cocoa.m which caters for pre-10.12
