Christophe JAILLET 1897c5c759 scsi: message: mptfc: 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 'mptfc_GetFcDevPage0()' GFP_KERNEL can be used
because it is already used in this function and no lock is acquired in the
between.

When memory is allocated in 'mptfc_GetFcPortPage0()' and
'mptfc_GetFcPortPage1()' GFP_KERNEL can be used because they already call
'mpt_config()' which has an explicit 'might_sleep()'.

While at it, also remove some useless casting.
