I'd suggest to rephase a bit, something like:
==
Introduce a helper ghes_edac_preferred(), which returns true when
ACPI GHES table is present and the platform-check passes on the system.
ghes_present is set once in ghes_probe() since ACPI GHES table is static.
==

Otherwise, the patch looks good to me.
