It tells to the callback that the firmware request fails [1].

/**
 * request_firmware_nowait:
 *
 * Description:
 *      Asynchronous variant of request_firmware() for contexts where
 *      it is not possible to sleep.
 *
 *      @hotplug invokes hotplug event to copy the firmware image if 
this flag
 *      is non-zero else the firmware copy must be done manually.
 *
 *      @cont will be called asynchronously when the firmware request 
is over.
 *
 *      @context will be passed over to @cont.
 *
 *      @fw may be %NULL if firmware request fails.
