* [PATCH] net: chelsio: switch from 'pci_' to 'dma_' API

  To: rajur, davem, kuba
  Cc: netdev, linux-kernel, kernel-janitors, Christophe JAILLET

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

It has been compile tested.
