Christophe JAILLET 3ab1270bfa smsc9420: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'smsc9420_probe()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

While at it, rewrite the size passed to 'dma_alloc_coherent()' the same way
as the one passed to 'dma_free_coherent()'. This form is less verbose:
   sizeof(struct smsc9420_dma_desc) * RX_RING_SIZE +
   sizeof(struct smsc9420_dma_desc) * TX_RING_SIZE,
vs
   sizeof(struct smsc9420_dma_desc) * (RX_RING_SIZE + TX_RING_SIZE)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
