Subject: [PATCH] bus: mhi: pci_generic: Simplify code and axe the use of a deprecated API
Git-commit: f3d13397365d834b3f882627a7962c76593eeef2
Patch-mainline: v5.17-rc1
References: bsc#1206451

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.
