[PATCH 1/3] crypto: qat - Simplify code and axe the use of a deprecated API
From: Christophe JAILLET
Date: Sun Jul 11 2021 - 02:13:36 EST
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.

If needed, see post from Christoph Hellwig on the kernel-janitors ML:
https://marc.info/?l=kernel-janitors&m=158745678307186&w=4
We could also reduce indentation by merging the 2 'if' together. If this
is the preferred style, I'll send a v2.
