[PATCH] staging: qlge: Remove pci-dma-compat wrapper APIs.

[Suraj Upadhyay <usuraj35@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 3839 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.
