backport of the megaraid_sas driver from kernel 4.14.20 to kernel 4.9.82


DMI: Intel Corporation S2600WFT/S2600WFT, BIOS
SE5C620.86B.00.01.0009.101920170742 10/19/2017

I copy /usr/src/linux-4.14.20/drivers/scsi/megaraid  to
/usr/src/linux-4.9.82/drivers/scsi/megaraid . I compile the kernel 4.9.82
and is OK !
I send dmesg atached.

The problem for original linux kernel 4.9.82 is :
