iommu/irq_remapping: Fix the regression of hpet irq remapping
Commit 71054d8841b4 ("x86, hpet: Introduce x86_msi_ops.setup_hpet_msi") introduced x86_msi_ops.setup_hpet_msi to setup hpet MSI irq when irq remapping enabled. This caused a regression of hpet MSI irq remapping. Original code flow before commit 71054d8841b4: hpet_setup_msi_irq() arch_setup_hpet_msi() setup_hpet_msi_remapped() remap_ops->setup_hpet_msi() alloc_irte() msi_compose_msg() hpet_msi_write() ... Current code flow after commit 71054d8841b4: hpet_setup_msi_irq() x86_msi.setup_hpet_msi() setup_hpet_msi_remapped() intel_setup_hpet_msi() alloc_irte() Currently, we only call alloc_irte() for hpet MSI, but do not composed and wrote its msg...
