Please look at the code blocks you are changing and
if you are trying to fix unbalanced else blocks, do
all the blocks, not just one of many consecutive.

		/* reject the command if the direction indicator
		 * is UNKNOWN
		 */
		if (chip->srb->sc_data_direction == DMA_BIDIRECTIONAL) {
			dev_err(&dev->pci->dev, "UNKNOWN data direction\n");
			chip->srb->result = DID_ERROR << 16;
		}

		/* reject if target != 0 or if LUN is higher than
		 * the maximum known LUN
		 */
		else if (chip->srb->device->id) {
			dev_err(&dev->pci->dev, "Bad target number (%d:%d)\n",
				chip->srb->device->id,
				(u8)chip->srb->device->lun);
			chip->srb->result = DID_BAD_TARGET << 16;
		}

		else if (chip->srb->device->lun > chip->max_lun) {
			dev_err(&dev->pci->dev, "Bad LUN (%d:%d)\n",
				chip->srb->device->id,
				(u8)chip->srb->device->lun);
			chip->srb->result = DID_BAD_TARGET << 16;
		}

		/* we've got a command, let's do it! */
		else {
			scsi_show_command(chip);
			rtsx_invoke_transport(chip->srb, chip);
		}
