I do not know that there is anything necessary to do here.
Per the discussion for that patch, the warning is just a warning and
while it is probably elevated higher than it should be (the patch only
seems to downgrade it to a DEBUG level message) it is innocuous.
The patch is landed in 6.13, for reference:

cxl: downgrade a warning message to debug level in
cxl_probe_component_regs()
In cxl_probe_component_regs() the error message "Couldn't locate the
CXL.cache and CXL.mem capability array header." is potentially a false
positive error condition.
Downgrade the message from error level to debug level by using dev_dbg()
to print the message, and the end users won't worry about the message
anymore.

We will take a look at this, but it is not a very high prioirty and may
not be accepted into the Ubuntu kernels.
