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;
}
