While unusual, intr_register_source() can return failure. A likely cause might be another device grabbing from Xen's interrupt range. This should NOT happen, but could happen due to a bug. As such check for this and fail if it occurs. This theoretical situation also effects xen_intr_find_unused_isrc(). There, .is_pic must be tested to ensure such an intrusion doesn't cause misbehavior.
