    Subject[PATCH V2 15/19] irqchip: crossbar: Add kerneldoc for crossbar_domain_unmap callback
    Date
    The crossbar_domain_map/unmap callbacks need not be called same number
    of times for a particular irq. But still use counting is not needed
    here, because unmap(irq) gets called when irq_desc(irq) is disposed.
    After this the irq is anyways unusable and have to mapped again.

    Adding the above kerneldoc for unmap callback clarity.
