Date: Thu, 16 Sep 2021 18:24:56 -0700 From: Qing Wang <wangqing@...o.com> To: Gustavo Pimentel <gustavo.pimentel@...opsys.com>, Vinod Koul <vkoul@...nel.org>, dmaengine@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Wang Qing <wangqing@...o.com> Subject: [PATCH] dma: dw-edma-pcie: switch from 'pci_' to 'dma_' API From: Wang Qing <wangqing@...o.com> The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below. expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) While at it, some 'dma_set_mask()/dma_set_coherent_mask()' have been updated to a much less verbose 'dma_set_mask_and_coherent()'. This type of patches has been going on for a long time, I plan to clean it up in the near future.
