Hi irqchip-bot,

Thank you for the patch! Perhaps something to improve:

cc1: some warnings being treated as errors

This makes zero sense. At the point where this patch is applied in
the series, all instances of irq_domain_add_legacy_isa() have been
removed, except for one in the Chinese translation of the documentation:

Are you applying the patches out of order, by any chance?

Thanks,
