Subject: [PATCH] ACPI/IORT: Remove the unused __get_pci_rid()

Since commit bc8648d49a95 ("ACPI/IORT: Handle PCI aliases properly for
IOMMUs"), __get_pci_rid() has become actually unused and can be removed.

Hi Will,

Could you please take this patch [*] into v5.8 (if it's not too late)?
I've tried and it can be applied to for-next/acpi cleanly.

Thanks,

If we miss v5.8 (which I think it is likely, even though this patch is
just removing dead code so it is safe at this stage) I will resend it
for v5.9 - not a problem.
