From 505b08777d78868e6c47051a4e7f011718a3aba1 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Tue, 1 Dec 2020 22:01:47 +0100 Subject: misc: genwqe: Use dma_set_mask_and_coherent to simplify code 'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose.
