Message-Id: <E1V50xi-0006sT-OX@rmk-PC.arm.linux.org.uk> Date: Thu, 01 Aug 2013 23:03:10 +0100 From: Russell King <rmk+kernel@....linux.org.uk> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, Arnd Bergmann <arnd@...db.de> Subject: [PATCH RFC 29/51] DMA-API: ata: pata_octeon_cf: convert to use dma_coerce_mask_and_coherent() Convert this code sequence: pdev->dev.coherent_dma_mask = DMA_BIT_MASK(64); pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask; to use dma_coerce_mask_and_coherent() to avoid bypassing the architecture check on the DMA mask.
