 CAUTION: This email originated from outside of the organization. Please make sure the sender is who they say they are and do not click links or open attachments unless you recognize the sender and know the content is safe.

When building kernels without ACPI support the table is declared
but is not used because ACPI_PTR() turns it into a NULL.

Add the __maybe_unused attribute to stop the compiler whining.

Ignore the first version. I'm an idiot and generated a patch,
check that it worked, noticed it didn't, fixed it up and then
forgot to regenerate the patch before sending it.
