Subject: [PATCH v1 08/23] ata: sata_dwc_460ex: don't call ata_sff_qc_issue() on DMA commands

From: Andy Shevchenko <[email-masked]>
Date: Thu, 21 Apr 2016 21:15:29 +0300

ata_sff_qc_issue() can't handle DMA commands and thus we have to avoid it for
them. Do call ata_bmdma_qc_issue() instead for this case.
