Christophe JAILLET 87f8c54423 mwifiex: switch from 'pci_' to 'dma_' API
[ Upstream commit 4cf975f640fefdfdf6168a79e882558478ce057a ]

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 'mwifiex_pcie_alloc_buffers()' (see details in
the call chain below) GFP_KERNEL can be used because both
'mwifiex_register()' and 'mwifiex_reinit_sw()' already use GFP_KERNEL.
(for 'mwifiex_reinit_sw()', it is hidden in a call to 'alloc_workqueue()')

The call chain is:
  mwifiex_register
    --> mwifiex_init_pcie        (.init_if function, see mwifiex_if_ops)
   [ or ]
  mwifiex_reinit_sw
    -->mwifiex_pcie_up_dev       (.up_dev function, see mwifiex_if_ops)

    [ then in both case ]
      -->mwifiex_pcie_alloc_buffers
        --> mwifiex_pcie_create_txbd_ring
        --> mwifiex_pcie_create_rxbd_ring
        --> mwifiex_pcie_create_evtbd_ring
        --> mwifiex_pcie_alloc_sleep_cookie_buf

README

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.
