OK, I think I misunderstood your explanation. Rather than judging based
on English emails, I went back and looked at the old and new code.
Looking at the old code, there is a clear 1-to-1-to-1-to-1
correspondence between adapter, request_irq() call, scsi_host, and
boardp. So what the old code is doing during probe is quite normal.
I thought you were saying there were multiple request_irq() calls for a
single adapter.
The only thing that's abnormal is the interrupt handler checking
multiple boards for events, which you rightly removed.
There is absolutely no need to add IRQF_SHARED to non-PCI devices or
anything like that.
At this point, looking at your new code, I would only add
"replace spin_lock_irqsave with spin_lock in interrupt handler"
and
"delete no-ops DvcEnterCritical and DvcLeaveCritical"
to the todo list.
