Remove the useless indirection. Signed-off-by: Thomas Gleixner --- V2: New patch. The same is probably true for lots of other irq chips. --- arch/x86/kernel/apic/msi.c | 1 - 1 file changed, 1 deletion(-) --- a/arch/x86/kernel/apic/msi.c +++ b/arch/x86/kernel/apic/msi.c @@ -278,7 +278,6 @@ static struct irq_chip pci_msi_ir_contro .irq_mask = pci_msi_mask_irq, .irq_ack = irq_chip_ack_parent, .irq_retrigger = irq_chip_retrigger_hierarchy, - .irq_set_vcpu_affinity = irq_chip_set_vcpu_affinity_parent, .flags = IRQCHIP_SKIP_SET_WAKE, };
