Subject: SCSI: pm80xx: fix Adaptec 71605H hang
From: Hans Verkuil <hverkuil@xxxxxxxxx>
commit 9504a923924d663e1953f872f0a828e6454a6cfc upstream.
The IO command size is 128 bytes for these new controllers as opposed to 64
for the old 8001 controller.
The Adaptec out-of-tree driver did this correctly. After comparing the two
this turned out to be the crucial difference.
So don't hardcode the IO command size, instead use pm8001_ha->iomb_size as
that is the correct value for both old and new controllers.
