[PATCH] scsi: hpsa and dc395x: Remove pci_dma_compat wrapper APIs.

[Suraj Upadhyay <usuraj35@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 5120 bytes --]

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
and compile-tested.
