Title:
smartpqi updates for ubuntu 18.04.2

Status in linux package in Ubuntu:
In Progress
Status in linux source package in Cosmic:
Fix Committed

Bug description:

== SRU Justification ==
Microsemi is requesting these five patches to be added to 18.04.2 to bring
the driver up to date with kernel.org and to correct issues seen
particularly on ARM systems. The 18.04.2 kernel will be 4.18 bases, so
this SRU request is for Cosmic.

All five of these commits cherry pick cleanly and are in mainline as of
v4.19-rc1.

== Fixes ==
957c5ab108c7 ("scsi: smartpqi: improve handling for sync requests")
26b390aba2a8 ("scsi: smartpqi: improve error checking for sync requests")
9f8d05fa9844 ("scsi: smartpqi: add inspur advantech ids")
dac12fbc7b0a ("scsi: smartpqi: fix critical ARM issue reading PQI index registers")
4ae5e9d159f8 ("scsi: smartpqi: bump driver version to 1.1.4-130")

== Regression Potential ==
Low. These five patches are limited to scsi/smartpqi.


This is a request to update the SmartPQI driver in Ubuntu kernel 18.04.2 by
pulling the following patches from upstream kernel version 4.19-rc7.

Microsemi would like added to Ubuntu 18.04.2 to bring the driver up to date with kernel.org and to
correct issues seen particularly on ARM systems.

These patches cherry-pick cleanly from:
