Send a response to an incoming request. By setting up an address range using the FW_CDEV_IOC_ALLOCATE ioctl, userspace can listen for incoming requests. An incoming request will generate an FW_CDEV_EVENT_REQUEST, and userspace must send a reply using this ioctl. The event has a handle to the kernel-side pending transaction, which should be used with this ioctl.
