Series aacraid: Host adapter Adaptec 6405 constantly resets under high io load | expand

Commit Message

The patch removes references to Series 9 adapters following
395e5df79a95 ("scsi: aacraid: Remove reference to Series-9"),
but doesn't touch Series 6 adapters logic.

Leaving Series 6 adapters untouched avoids controller
hungs/resets under high io load.

We'll need some guidance from the Microsemi folks on this issue.

These two links don't appear to be publicly accessible and therefore do
not belong in the patch.
