[SRU,F-hwe-5.11,00/30] Update SmartPQI driver

BugLink: https://bugs.launchpad.net/bugs/1933518

[Impact]

* Microchip asks to update the SCSI SmartPQI driver to latest version
  from upstream Linux kernel.
* This contains mostly fixes and refactorings.
* Updated driver allows to support properly latest SmartPQI controllers.

[Fix]

* Cherry-pick all the patches related to smartpqi.
* These are clean picks although the patchset is pretty big.

[Test Plan]

* Build-test each commit.
* Asked Microhip to perform the testing. Received feedback:
  "I installed the provided kernel package and thus far performed:
  1. reboot tests
  2. insmod/rmmod tests
  3. fio testing: no performance regressions"

[Where problems could occur]

* The patches touch only smartpqi driver so the scope of possible
  failures is limited to systems which probe it (so basically systems
  with SmartPQI controller).
* On such SmartPQI-equipped systems the patchset can cause data corruption,
  data loss or unavailability of SCSI storage and boot failure.

Best regards,
Krzysztof

Hi Krzysztof,

We usually don't apply patches directly to the hwe kernels, unless strictly
necessary. In this case it would be better to submit the patches hirsute/linux
and they will get applied automatically to focal/linux-hwe-5.11 on the next
rebase.

We also suggest that for large series it would be better to review and apply
the patches if they are sent as a pull request.

Could you please re-send this series for hirsute/linux?


Thanks,
Kleber
