    Subject[PATCH v9 17/34] usb: host: xhci-plat: Set XHCI max interrupters if property is present
    Date
    Some platforms may want to limit the number of XHCI interrupters allocated.
    This is passed to xhci-plat as a device property. Ensure that this is read
    and the max_interrupters field is set.
