[PATCH] scsi: hpsa: prevent hpsa to severly delay boot

[PATCH] scsi: hpsa: prevent hpsa to severly delay boot

[Corentin Labbe]

On my HPE Proliant microserver gen 10+, modprobing hpsa lead to:
hpsa 0000:01:00.7: unrecognized board ID: 0x00e41590
hpsa 0000:01:00.7: unrecognized board ID: 0x00e41590
hpsa 0000:01:00.7: can't disable ASPM; OS doesnt't have ASPM control
hpsa 0000:01:00.7: board not ready, timed out.

And the boot is severly delayed until the timeout.

The controller is HPE Smart Array S100i SR Gen10

I have tried to add (naivly) to struct board_type products:
	{0x00e41590, "Smart Array S100i SR Gen10", &SA5_access},
but the board still time out.

With further search, I found that the S100i seems to be a fake SW RAID controller usefull for windows only.

So I use the following patch to fix the boot stuck.

The same happens with ProLiant DL360 Gen10.

Also confirmed on ProLiant DL360 Gen10 as working, but not sure about 
the general approach.
