This has been irritating me as well. Need to do
drivers/perf/cxl_pmu.c at somepoint as well but given that goes through
a different maintainer makes sense to do separately.
Only comment I have is that we should probably strive for more consistency
than you currently have. Always expand CXL or never do, use
colons consistently, use Support everywhere or nowhere.

Why the expanded version for this one?
I'm not sure Devices really makes sense here, particularly as it
likely a range of other driver will make some use of this core
functionality over time. Maybe "CXL core" is sufficient?

Why does this one get a colon? Also no Support at the end?
