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.
