Subject: [PATCH 4/7] scsi: mpt3sas: Remove pci-dma-compat wrapper APIs.
The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs.
Instead use dma-mapping.h APIs directly.
The patch has been generated with the coccinelle script below.
Compile tested.
