[PATCH 19/23] um: virt-pci: Use irq_domain_instantiate()

um_pci_init() uses __irq_domain_add(). With the introduction of irq_domain_instantiate(), __irq_domain_add() becomes obsolete. In order to fully remove __irq_domain_add(), use directly irq_domain_instantiate(). Signed-off-by: Herve Codina --- arch/um/drivers/virt-pci.c | 16 ++-- 1

[PATCH 20/23] irqdomain: Remove __irq_domain_add()
