Commit Message

Christophe JAILLET Jan. 2, 2022, 11:44 a.m. UTC 
In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation.
Only relevant parts are given below.
