From 53b50458110d829c8fc45e7803a335a515698fd8 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Thu, 8 Jul 2021 07:08:26 +0200 Subject: [PATCH] dmaengine: idxd: Simplify code and axe the use of a deprecated API The wrappers in include/linux/pci-dma-compat.h should go away. Replace 'pci_set_dma_mask/pci_set_consistent_dma_mask' by an equivalent and less verbose 'dma_set_mask_and_coherent()' call. Even if the code may look different, it should have exactly the same run-time behavior. If pci_set_dma_mask(64) fails and pci_set_dma_mask(32) succeeds, then pci_set_consistent_dma_mask(64) will also fail.
