If Value for the false possibility is greater at compile time(irq_default_domain == domain) Then q_set_default_host() - Set a "default" irq domain*@domain: default domain pointer* For convenience, it's possible to set a "default" domain that will be used* whenever NULL is passed to irq_create_mapping()
