Looks like we need:

diff --git a/drivers/scsi/aic94xx/aic94xx_init.c

I have no strong feelings either way, but aic94xx and mvsas
maintainers have been hard to reach and I'm not encouraged more time
will yield a different result versus just moving ahead with these
fixes.

That said we still have Tom's discovery regression which is a separate issue.
