    Subject[patch 08/39] genirq/msi: Provide msi_domain_ops::post_free()
    Date
    To prepare for removing the exposure of __msi_domain_free_irqs() provide a
    post_free() callback in the MSI domain ops which can be used to solve
    the problem of the only user of __msi_domain_free_irqs() in arch/powerpc.
