The attached patch is a one-line change to linux-pm 5.16-rc8.

The patch simply adds ACPI_SIG_CEDT to table_sigs[] in 
"drivers/acpi/tables.c".

Presently, CXL code isn't able to make use of the CEDT table. Subsequent 
to the change, the CEDT table can be used.

If a developer plans to use the CEDT table to program the CXL ports, 
this change is needed. Otherwise, it isn't expected to make a difference.

If this should go to linux-acpi as opposed to linux-pm, please excuse 
the error.
