Subject: [PATCH net-next v2] gve: Simplify code and axe the use of a deprecated API
Date:   Thu,  1 Jul 2021 22:41:19 +0200
Message-Id: <a8ff6511e4740cff2bb549708b98fb1e6dd7e070.1625172036.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
