Commit Message

Christophe JAILLET June 13, 2021, 10:26 a.m.
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.

In all these places where some memory is allocated GFP_KERNEL can be used
because they already call 'mpt_config()' which has an explicit
'might_sleep()'.
