[SCSI] ibmmca: convert to new probing API and fix oopses
This is basically a straight conversion. I have one of these things, so I know it works ... my problem is that it has a wierd SCA like connector, so I can't connect anything to it (no cables). However, previously it panic'd in the interrupt, now it completes a bus scan. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
