 * crossbar_domain_unmap - unmap a crossbar<->irq connection

 * @d: domain of irq to unmap

 * @irq: virq number

 *

 * We do not maintain a use count of total number of map/unmap

 * calls for a particular irq to find out if a irq can be really

 * unmapped. This is because unmap is called during irq_dispose_mapping(irq),

 * after which irq is anyways unusable. So an explicit map has to be called

 * after that.
