[PATCH] mwifiex: switch from 'pci_' to 'dma_' API

From: Christophe JAILLET
Date: Wed Aug 19 2020 - 03:03:01 EST

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
