Date: Sat, 21 Nov 2020 10:03:02 +0100 From: Christophe JAILLET <christophe.jaillet@...adoo.fr> To: davem@...emloft.net, kuba@...nel.org, kaixuxia@...cent.com, mhabets@...arflare.com, mst@...hat.com, luc.vanoostenryck@...il.com, jesse.brandeburg@...el.com Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Christophe JAILLET <christophe.jaillet@...adoo.fr> Subject: [PATCH 1/2] net: pch_gbe: 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.
