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

HEAD is now at bf541b2ef87c irqdomain: Kill irq_domain_add_legacy_isa
maz@hot-poop:~/arm-platforms$ git grep irq_domain_add_legacy_isa
Documentation/translations/zh_CN/core-api/irq/irq-domain.rst:   
irq_domain_add_legacy_isa()

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