Should we display an error message if we don't find a matching table?
That can happen if the ACPI tables shows a GIC version number that is
not listed in __irqchip_acpi_table[]?
Hmm, did you get the error message like: "Invalid GIC version 5 in
MADT"? or just use ACPI_MADT_GIC_VERSION_V1 as the gic_version? if
the later one, it will show everything is fine, but failed to probe
the GIC.
I agree with you that we need to print some error message here,
I will update my patch.
Thanks
