Please make the code ahear to Documentation/CodingStyle (aka the style
used everywhere else in ahci.c..)

Something like:

static int ahci_check_atapi_dma(struct ata_queued_cmd *qc)
	struct pci_dev *pdev = to_pci_dev(qc->ap->host->dev);

	 * Walkaround for ATI/AMD SB600 SATA ODD isue.
	if (pdev->vendor = PCI_VENDOR_ID_ATI && pdev->device == 0x4380) {
		struct ahci_host_priv *priv = qc->ap->host->private_data;

		if (priv->rev < 14) {
			u32 rq_len = qc->scsicmd->request_bufflen;
			u32 low_8k = rq_len & 0x1fff;

			if ((rq_len & 0xffffe000) && low_8k && low_8k < 512)
        	               	return 1;

	return 0;
