   500	 * @return: true if the AI engine partition is not in use, otherwise, false
   501	 *
   502	 * This function looks up the AI engine class devices to find the AI engine
   503	 * partition whose partition ID matches the given partition ID in @req. If
   504	 * the partition can be found, if will check if the partition is in use.
   505	 *
   506	 * In case the AI engine release function is called from kernel context, the
   507	 * release() will be scheduled when the AI engine partition reference count is
   508	 * reduced to 0 instead of get called synchronously, and thus, this is a helper
   509	 * function for another kernel module to check if the partitions is released
   510	 * after calling release function from kernel context
   511	 *
   512	 * However, if closing the partition is from user context, it will not return
   513	 * until the release is complete when there is no reference to the AI engine
   514	 * partition file. In this case, user doesn't need to call this function to
   515	 * check if the partition is released.
